Doc Text:
A flaw was found in the Linux kernel's Qualcomm Venus driver. When processing firmware messages from shared memory, the driver fails to properly validate that the packet size does not exceed the available buffer boundaries. A local user could exploit this vulnerability to trigger an out-of-bounds memory access, potentially causing a system crash and Denial of Service (DoS).

Description OSIDB Bzimport 2025-09-05 18:02:26 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: venus: Add a check for packet size after reading from shared memory

Add a check to ensure that the packet size does not exceed the number of
available words after reading the packet header from shared memory. This
ensures that the size provided by the firmware is safe to process and
prevent potential out-of-bounds memory access.
