| Improper Following of a Certificate's Chain of Trust vulnerability in Erlang OTP public_key (pubkey_cert module) allows a non-CA certificate to be accepted as an intermediate issuer, enabling certificate chain forgery.
In lib/public_key/src/pubkey_cert.erl, pubkey_cert:validate_extensions/7 contains two flaws that together allow a certificate with basicConstraints cA:false and no keyUsage extension to be used as an intermediate issuer in a chain passed to public_key:pkix_path_validation/3: the cA:false clause recurses into the remaining extensions without rejecting the certificate when it is in issuer position, and the keyUsage check only fires when the extension is present, so a certificate lacking keyUsage entirely bypasses the keyCertSign enforcement.
Any party holding an end-entity certificate with basicConstraints cA:false and no keyUsage extension, issued by any CA in the victim's trust store, can use that certificate's private key to sign forged leaf certificates for arbitrary identities. public_key:pkix_path_validation/3 accepts the resulting chain, and by extension every TLS or mTLS endpoint built on the OTP ssl application that relies on the default verifier is affected, including server identity verification on the client side and client certificate verification on mTLS servers.
This issue affects OTP from OTP 17.0 before OTP 26.2.5.21, 27.3.4.12, 28.5.0.1, and 29.0.1 corresponding to public_key from 0.22 before 1.15.1.7, 1.17.1.3, 1.20.3.1, and 1.21.1. |
| A vulnerability was detected in TeamSpeak 3 Server up to 3.13.7. This issue affects some unknown processing of the component clientek Handshake Handler. Performing a manipulation of the argument proof results in reachable assertion. Remote exploitation of the attack is possible. Upgrading to version 3.13.8 is capable of addressing this issue. Upgrading the affected component is recommended. |
| Budibase is an open-source low-code platform. Prior to 3.39.0, the Budibase Text component renders markdown by assigning marked.parse(markdown) straight to innerHTML with no sanitizer (packages/bbui/src/Markdown/MarkdownViewer.svelte:22). Any column a builder binds to a Text component in Markdown mode is a stored-XSS sink writable by every BASIC app user with WRITE on the underlying table. This vulnerability is fixed in 3.39.0. |
| Budibase is an open-source low-code platform. Prior to 3.39.0, the webhook schema-building endpoint is registered under builderRoutes, but the generic authorization middleware skips authorization for all paths matching /api/webhooks/schema. As a result, an unauthenticated caller can update the body schema for a known webhook and mutate the corresponding automation trigger output schema. This vulnerability is fixed in 3.39.0. |
| Budibase is an open-source low-code platform. Prior to 3.39.0, the single-datasource GET and PUT routes are guarded by generic TABLE READ, not by Builder/Admin permission or datasource-specific ownership/resource checks. The built-in Basic app user role maps to the WRITE permission set, which includes table read/write and query write. A Basic user can therefore read an existing REST datasource, receive redacted authConfigs values, submit an update that changes only config.url while keeping the redacted placeholders, and trigger an existing saved relative-path REST query. During update, mergeConfigs() restores the old stored secret when it sees the redaction placeholder. During query execution, Budibase prefixes the attacker-controlled datasource config.url to the relative query path and applies the resolved stored auth headers. The result is server-side disclosure of the builder-configured REST Authorization secret to an attacker-controlled listener. This vulnerability is fixed in 3.39.0. |
| Command injection in Raynet rvia 12.6.4392.49-amd64.deb allows adversaries to execute commands via getconfig, and upload through the URL argument, and oracle through the -o flag The Supplier's perspective is that this is caused by Argument Injection in the find command query in rvia 12.6.4392.49. This in an arbitrary code execution flaw caused by an incorrectly constructed find command. The application actively searches for a Java executable by using search criteria that is not properly terminated or sanitized. By constructing a crafted directory path that satisfies the malformed search criteria, an attacker can trick the application into executing arbitrary Java code. This differs from standard PATH manipulation because it stems from the application's internal search logic. Specifically, a local attacker can create a crafted directory structure and path that satisfies an improperly terminated find query used by the application to locate a Java runtime. |
| Budibase is an open-source low-code platform. Prior to 3.35.10, the Plugin URL upload endpoint (POST /api/plugin) validates the submitted URL with a single substring check: url.includes(".tar.gz"). Any URL containing .tar.gz anywhere in the string — in the path, query string, or fragment — passes this check. The URL then proceeds directly to fetchWithBlacklist() with no further validation of host, scheme, or path. Standalone, this vulnerability is blocked by Budibase's default SSRF blacklist, which covers private IP ranges. But the URL validation layer itself is broken regardless, and it directly enables SSRF in two realistic situations: (1) when chained with the BLACKLIST_IPS bypass ([001]), where the blacklist is empty; and (2) when the plugin server follows HTTP redirects from an external URL to an internal target (the default node-fetch behavior with redirect: 'follow'). This vulnerability is fixed in 3.35.10. |
| Authentication bypass using an alternate path or channel in Microsoft Azure Active Directory B2C allows an unauthorized attacker to elevate privileges over a network. |
| Authorization bypass through user-controlled key in Azure Privileged Identity Management (PIM) allows an authorized attacker to elevate privileges over a network. |
| Improper input validation in Azure Virtual Network Gateway allows an authorized attacker to execute code over a network. |
| In the Linux kernel, the following vulnerability has been resolved:
apparmor: avoid per-cpu hold underflow in aa_get_buffer
When aa_get_buffer() pulls from the per-cpu list it unconditionally
decrements cache->hold. If hold reaches 0 while count is still non-zero,
the unsigned decrement wraps to UINT_MAX. This keeps hold non-zero for a
very long time, so aa_put_buffer() never returns buffers to the global
list, which can starve other CPUs and force repeated kmalloc(aa_g_path_max)
allocations.
Guard the decrement so hold never underflows. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix bpf_xdp_store_bytes proto for read-only arg
While making some maps in Cilium read-only from the BPF side, we noticed
that the bpf_xdp_store_bytes proto is incorrect. In particular, the
verifier was throwing the following error:
; ret = ctx_store_bytes(ctx, l3_off + offsetof(struct iphdr, saddr),
&nat->address, 4, 0);
635: (79) r1 = *(u64 *)(r10 -144) ; R1=ctx() R10=fp0 fp-144=ctx()
636: (b4) w2 = 26 ; R2=26
637: (b4) w4 = 4 ; R4=4
638: (b4) w5 = 0 ; R5=0
639: (85) call bpf_xdp_store_bytes#190
write into map forbidden, value_size=6 off=0 size=4
nat comes from a BPF_F_RDONLY_PROG map, so R3 is a PTR_TO_MAP_VALUE.
The verifier checks the helper's memory access to R3 in
check_mem_size_reg, as it reaches ARG_CONST_SIZE argument. The third
argument has expected type ARG_PTR_TO_UNINIT_MEM, which includes the
MEM_WRITE flag. The verifier thus checks for a BPF_WRITE access on R3.
Given R3 points to a read-only map, the check fails.
Conversely, ARG_PTR_TO_UNINIT_MEM can also lead to the helper reading
from uninitialized memory.
This patch simply fixes the expected argument type to match that of
bpf_skb_store_bytes. |
| In the Linux kernel, the following vulnerability has been resolved:
md/raid1: fix memory leak in raid1_run()
raid1_run() calls setup_conf() which registers a thread via
md_register_thread(). If raid1_set_limits() fails, the previously
registered thread is not unregistered, resulting in a memory leak
of the md_thread structure and the thread resource itself.
Add md_unregister_thread() to the error path to properly cleanup
the thread, which aligns with the error handling logic of other paths
in this function.
Compile tested only. Issue found using a prototype static analysis tool
and code review. |
| In the Linux kernel, the following vulnerability has been resolved:
xen-netback: reject zero-queue configuration from guest
A malicious or buggy Xen guest can write "0" to the xenbus key
"multi-queue-num-queues". The connect() function in the backend only
validates the upper bound (requested_num_queues > xenvif_max_queues)
but not zero, allowing requested_num_queues=0 to reach
vzalloc(array_size(0, sizeof(struct xenvif_queue))), which triggers
WARN_ON_ONCE(!size) in __vmalloc_node_range().
On systems with panic_on_warn=1, this allows a guest-to-host denial
of service.
The Xen network interface specification requires
the queue count to be "greater than zero".
Add a zero check to match the validation already present
in xen-blkback, which has included this
guard since its multi-queue support was added. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: revert commit_mutex usage in reset path
It causes circular lock dependency between commit_mutex, nfnl_subsys_ipset
and nlk_cb_mutex when nft reset, ipset list, and iptables-nft with '-m set'
rule run at the same time.
Previous patches made it safe to run individual reset handlers concurrently
so commit_mutex is no longer required to prevent this. |
| In the Linux kernel, the following vulnerability has been resolved:
powerpc/eeh: fix recursive pci_lock_rescan_remove locking in EEH event handling
The recent commit 1010b4c012b0 ("powerpc/eeh: Make EEH driver device
hotplug safe") restructured the EEH driver to improve synchronization
with the PCI hotplug layer.
However, it inadvertently moved pci_lock_rescan_remove() outside its
intended scope in eeh_handle_normal_event(), leading to broken PCI
error reporting and improper EEH event triggering. Specifically,
eeh_handle_normal_event() acquired pci_lock_rescan_remove() before
calling eeh_pe_bus_get(), but eeh_pe_bus_get() itself attempts to
acquire the same lock internally, causing nested locking and disrupting
normal EEH event handling paths.
This patch adds a boolean parameter do_lock to _eeh_pe_bus_get(),
with two public wrappers:
eeh_pe_bus_get() with locking enabled.
eeh_pe_bus_get_nolock() that skips locking.
Callers that already hold pci_lock_rescan_remove() now use
eeh_pe_bus_get_nolock() to avoid recursive lock acquisition.
Additionally, pci_lock_rescan_remove() calls are restored to the correct
position—after eeh_pe_bus_get() and immediately before iterating affected
PEs and devices. This ensures EEH-triggered PCI removes occur under proper
bus rescan locking without recursive lock contention.
The eeh_pe_loc_get() function has been split into two functions:
eeh_pe_loc_get(struct eeh_pe *pe) which retrieves the loc for given PE.
eeh_pe_loc_get_bus(struct pci_bus *bus) which retrieves the location
code for given bus.
This resolves lockdep warnings such as:

accel/amdxdna: Fix memory leak in amdxdna_ubuf_map
The amdxdna_ubuf_map() function allocates memory for sg and
internal sg table structures, but it fails to free them if subsequent
operations (sg_alloc_table_from_pages or dma_map_sgtable) fail. |

Revert "hwmon: (ibmpex) fix use-after-free in high/low store"
This reverts commit 6946c726c3f4c36f0f049e6f97e88c510b15f65d.
Jean Delvare points out that the patch does not completely
fix the reported problem, that it in fact introduces a
(new) race condition, and that it may actually not be needed in
the first place.
Various AI reviews agree. Specific and relevant AI feedback:
"
This reordering sets the driver data to NULL before removing the sensor
attributes in the loop below.
ibmpex_show_sensor() retrieves this driver data via dev_get_drvdata() but
does not check if it is NULL before dereferencing it to access
data->sensors[].
If a userspace process reads a sensor file (like temp1_input) while this
delete function is running, could it race with the dev_set_drvdata(...,
NULL) call here and crash in ibmpex_show_sensor()?
Would it be safer to keep the original order where device_remove_file() is
called before clearing the driver data? device_remove_file() should wait
for any active sysfs callbacks to complete, which might already prevent the
use-after-free this patch intends to fix.
"
Revert the offending patch. If it can be shown that the originally reported
alleged race condition does indeed exist, it can always be re-introduced
with a complete fix. |
| In the Linux kernel, the following vulnerability has been resolved:
fat: avoid parent link count underflow in rmdir
Corrupted FAT images can leave a directory inode with an incorrect
i_nlink (e.g. 2 even though subdirectories exist). rmdir then
unconditionally calls drop_nlink(dir) and can drive i_nlink to 0,
triggering the WARN_ON in drop_nlink().
Add a sanity check in vfat_rmdir() and msdos_rmdir(): only drop the
parent link count when it is at least 3, otherwise report a filesystem
error. |
| In the Linux kernel, the following vulnerability has been resolved:
power: supply: sbs-battery: Fix use-after-free in power_supply_changed()
Using the `devm_` variant for requesting IRQ _before_ the `devm_`
variant for allocating/registering the `power_supply` handle, means that
the `power_supply` handle will be deallocated/unregistered _before_ the
interrupt handler (since `devm_` naturally deallocates in reverse
allocation order). This means that during removal, there is a race
condition where an interrupt can fire just _after_ the `power_supply`
handle has been freed, *but* just _before_ the corresponding
unregistration of the IRQ handler has run.
This will lead to the IRQ handler calling `power_supply_changed()` with
a freed `power_supply` handle. Which usually crashes the system or
otherwise silently corrupts the memory...
Note that there is a similar situation which can also happen during
`probe()`; the possibility of an interrupt firing _before_ registering
the `power_supply` handle. This would then lead to the nasty situation
of using the `power_supply` handle *uninitialized* in
`power_supply_changed()`.
Fix this racy use-after-free by making sure the IRQ is requested _after_
the registration of the `power_supply` handle. Keep the old behavior of
just printing a warning in case of any failures during the IRQ request
and finishing the probe successfully. |
