| NULL Pointer Dereference vulnerability in ravynsoft ravynos.This issue affects ravynos: through 0.5.2. |
| In the Linux kernel, the following vulnerability has been resolved:
genirq/ipi: Fix NULL pointer deref in irq_data_get_affinity_mask()
If ipi_send_{mask|single}() is called with an invalid interrupt number, all
the local variables there will be NULL. ipi_send_verify() which is invoked
from these functions does verify its 'data' parameter, resulting in a
kernel oops in irq_data_get_affinity_mask() as the passed NULL pointer gets
dereferenced.
Add a missing NULL pointer check in ipi_send_verify()...
Found by Linux Verification Center (linuxtesting.org) with the SVACE static
analysis tool. |
| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Enhance sanity check while generating attr_list
ni_create_attr_list uses WARN_ON to catch error cases while generating
attribute list, which only prints out stack trace and may not be enough.
This repalces them with more proper error handling flow.

| In the Linux kernel, the following vulnerability has been resolved:
powerpc: Don't try to copy PPR for task with NULL pt_regs
powerpc sets up PF_KTHREAD and PF_IO_WORKER with a NULL pt_regs, which
from my (arguably very short) checking is not commonly done for other
archs. This is fine, except when PF_IO_WORKER's have been created and
the task does something that causes a coredump to be generated. Then we
get this crash:

| In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: dp: Change logging to dev for mtk_dp_aux_transfer()
Change logging from drm_{err,info}() to dev_{err,info}() in functions
mtk_dp_aux_transfer() and mtk_dp_aux_do_transfer(): this will be
essential to avoid getting NULL pointer kernel panics if any kind
of error happens during AUX transfers happening before the bridge
is attached.
This may potentially start happening in a later commit implementing
aux-bus support, as AUX transfers will be triggered from the panel
driver (for EDID) before the mtk-dp bridge gets attached, and it's
done in preparation for the same. |
| In the Linux kernel, the following vulnerability has been resolved:
i2c: mux: reg: check return value after calling platform_get_resource()
It will cause null-ptr-deref in resource_size(), if platform_get_resource()
returns NULL, move calling resource_size() after devm_ioremap_resource() that
will check 'res' to avoid null-ptr-deref.
And use devm_platform_get_and_ioremap_resource() to simplify code. |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: wmt-sdmmc: fix return value check of mmc_add_host()
mmc_add_host() may return error, if we ignore its return value, the memory
that allocated in mmc_alloc_host() will be leaked and it will lead a kernel
crash because of deleting not added device in the remove path.
So fix this by checking the return value and goto error path which will call
mmc_free_host(), besides, clk_disable_unprepare() also needs be called. |

When the default qdisc is sfb, if the qdisc of dev_queue fails to be

In this case, the q->qdisc is NULL, and it will cause gpf issue.

Remote Denial of Service can occur because of incorrect deserialization that results in failed memory allocation and a NULL pointer dereference. |

| Envoy is a high-performance edge/middle/service proxy. In 1.33.12, 1.34.10, 1.35.6, 1.36.2, and earlier, Envoy crashes when JWT authentication is configured with the remote JWKS fetching, allow_missing_or_failed is enabled, multiple JWT tokens are present in the request headers and the JWKS fetch fails. This is caused by a re-entry bug in the JwksFetcherImpl. When the first token's JWKS fetch fails, onJwksError() callback triggers processing of the second token, which calls fetch() again on the same fetcher object. The original callback's reset() then clears the second fetch's state (receiver_ and request_) which causes a crash when the async HTTP response arrives. |

| Omni manages Kubernetes on bare metal, virtual machines, or in a cloud. Prior to 1.1.5 and 1.0.2, there is a nil pointer dereference vulnerability in the Omni Resource Service allows unauthenticated users to cause a server panic and denial of service by sending empty create/update resource requests through the API endpoints. The vulnerability exists in the isSensitiveSpec function which calls grpcomni.CreateResource without checking if the resource's metadata field is nil. When a resource is created with an empty Metadata field, the CreateResource function attempts to access resource.Metadata.Version causing a segmentation fault. This vulnerability is fixed in 1.1.5 and 1.0.2. |
