CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
cachestat: do not flush stats in recency check
syzbot detects that cachestat() is flushing stats, which can sleep, in its
RCU read section (see [1]). This is done in the workingset_test_recent()
step (which checks if the folio's eviction is recent).
Move the stat flushing step to before the RCU read section of cachestat,
and skip stat flushing during the recency check.

| In the Linux kernel, the following vulnerability has been resolved:
mmc: davinci_mmc: Prevent transmitted data size from exceeding sgm's length
No check is done on the size of the data to be transmiited. This causes
a kernel panic when this size exceeds the sg_miter's length.
Limit the number of transmitted bytes to sgm->length. |
| Sourcecodester Markdown to HTML Converter v1.0 is vulnerable to a Cross-Site Scripting (XSS) in the "Markdown Input" field, allowing a remote attacker to inject arbitrary HTML/JavaScript code that executes in the victim's browser upon clicking the "Convert to HTML" button. |
| A Server-Side Request Forgery (SSRF) in JGM Pandoc v3.6.4 allows attackers to gain access to and compromise the whole infrastructure via injecting a crafted iframe. |
| VMware Aria Operations and VMware Tools contain a local privilege escalation vulnerability. A malicious local actor with non-administrative privileges having access to a VM with VMware Tools installed and managed by Aria Operations with SDMP enabled may exploit this vulnerability to escalate privileges to root on the same VM. |
| Insufficiently Protected Credentials in the Crowdstrike connector can lead to Crowdstrike credentials being leaked. A malicious user can access cached credentials from a Crowdstrike connector in another space by creating and running a Crowdstrike connector in a space to which they have access. |
| A vulnerability was detected in SourceCodester Hotel and Lodge Management System 1.0. This impacts an unknown function of the file /del_room.php. The manipulation of the argument ID results in sql injection. The attack can be executed remotely. The exploit is now public and may be used. |
| A security vulnerability has been detected in SourceCodester Hotel and Lodge Management System 1.0. This affects an unknown function of the file /pages/save_room.php. The manipulation of the argument floorno leads to sql injection. Remote exploitation of the attack is possible. The exploit has been disclosed publicly and may be used. |
| A potential security vulnerability has been identified in HP Sure Start’s protection of the Intel Flash Descriptor in certain HP PC products, which might allow security bypass, arbitrary code execution, loss of integrity or confidentiality, or denial of service. HP is releasing BIOS updates to mitigate the potential vulnerability. |
| In the Linux kernel, the following vulnerability has been resolved:
tty: serial: samsung_tty: Fix a memory leak in s3c24xx_serial_getclk() when iterating clk
When the best clk is searched, we iterate over all possible clk.
If we find a better match, the previous one, if any, needs to be freed.
If a better match has already been found, we still need to free the new
one, otherwise it leaks. |
| In the Linux kernel, the following vulnerability has been resolved:
net/handshake: fix null-ptr-deref in handshake_nl_done_doit()
We should not call trace_handshake_cmd_done_err() if socket lookup has failed.
Also we should call trace_handshake_cmd_done_err() before releasing the file,
otherwise dereferencing sock->sk can return garbage.
This also reverts 7afc6d0a107f ("net/handshake: Fix uninitialized local variable")

| In the Linux kernel, the following vulnerability has been resolved:
tun: Fix memory leak for detached NAPI queue.
syzkaller reported [0] memory leaks of sk and skb related to the TUN
device with no repro, but we can reproduce it easily with:
struct ifreq ifr = {}
int fd_tun, fd_tmp;
char buf[4] = {};
fd_tun = openat(AT_FDCWD, "/dev/net/tun", O_WRONLY, 0);
ifr.ifr_flags = IFF_TUN | IFF_NAPI | IFF_MULTI_QUEUE;
ioctl(fd_tun, TUNSETIFF, &ifr);
ifr.ifr_flags = IFF_DETACH_QUEUE;
ioctl(fd_tun, TUNSETQUEUE, &ifr);
fd_tmp = socket(AF_PACKET, SOCK_PACKET, 0);
ifr.ifr_flags = IFF_UP;
ioctl(fd_tmp, SIOCSIFFLAGS, &ifr);
write(fd_tun, buf, sizeof(buf));
close(fd_tun);
If we enable NAPI and multi-queue on a TUN device, we can put skb into
tfile->sk.sk_write_queue after the queue is detached. We should prevent
it by checking tfile->detached before queuing skb.
Note this must be done under tfile->sk.sk_write_queue.lock because write()
and ioctl(IFF_DETACH_QUEUE) can run concurrently. Otherwise, there would
be a small race window:
write() ioctl(IFF_DETACH_QUEUE)
`- tun_get_user `- __tun_detach
|- if (tfile->detached) |- tun_disable_queue
| `-> false | `- tfile->detached = tun
| `- tun_queue_purge
|- spin_lock_bh(&queue->lock)
`- __skb_queue_tail(queue, skb)
Another solution is to call tun_queue_purge() when closing and
reattaching the detached queue, but it could paper over another
problems. Also, we do the same kind of test for IFF_NAPI_FRAGS.

| In the Linux kernel, the following vulnerability has been resolved:
xfrm: Zero padding when dumping algos and encap
When copying data to user-space we should ensure that only valid
data is copied over. Padding in structures may be filled with
random (possibly sensitve) data and should never be given directly
to user-space.
This patch fixes the copying of xfrm algorithms and the encap
template in xfrm_user so that padding is zeroed. |
| In the Linux kernel, the following vulnerability has been resolved:
fs: hfsplus: remove WARN_ON() from hfsplus_cat_{read,write}_inode()
syzbot is hitting WARN_ON() in hfsplus_cat_{read,write}_inode(), for
crafted filesystem image can contain bogus length. There conditions are
not kernel bugs that can justify kernel to panic. |
| In the Linux kernel, the following vulnerability has been resolved:
hwmon: (xgene) Fix ioremap and memremap leak
Smatch reports:
drivers/hwmon/xgene-hwmon.c:757 xgene_hwmon_probe() warn:
'ctx->pcc_comm_addr' from ioremap() not released on line: 757.
This is because in drivers/hwmon/xgene-hwmon.c:701 xgene_hwmon_probe(),
ioremap and memremap is not released, which may cause a leak.
To fix this, ioremap and memremap is modified to devm_ioremap and
devm_memremap.

| In the Linux kernel, the following vulnerability has been resolved:
bcache: Fix __bch_btree_node_alloc to make the failure behavior consistent
In some specific situations, the return value of __bch_btree_node_alloc
may be NULL. This may lead to a potential NULL pointer dereference in
caller function like a calling chain :
btree_split->bch_btree_node_alloc->__bch_btree_node_alloc.
Fix it by initializing the return value in __bch_btree_node_alloc. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSD: Avoid calling OPDESC() with ops->opnum == OP_ILLEGAL
OPDESC() simply indexes into nfsd4_ops[] by the op's operation
number, without range checking that value. It assumes callers are
careful to avoid calling it with an out-of-bounds opnum value.
nfsd4_decode_compound() is not so careful, and can invoke OPDESC()
with opnum set to OP_ILLEGAL, which is 10044 -- well beyond the end
of nfsd4_ops[]. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt7601u: fix an integer underflow
Fix an integer underflow that leads to a null pointer dereference in
'mt7601u_rx_skb_from_seg()'. The variable 'dma_len' in the URB packet
could be manipulated, which could trigger an integer underflow of
'seg_len' in 'mt7601u_rx_process_seg()'. This underflow subsequently
causes the 'bad_frame' checks in 'mt7601u_rx_skb_from_seg()' to be
bypassed, eventually leading to a dereference of the pointer 'p', which
is a null pointer.
Ensure that 'dma_len' is greater than 'min_seg_len'.
Found by a modified version of syzkaller.
