Описание
In the Linux kernel, the following vulnerability has been resolved:
drm/xe/sync: Fix user fence leak on alloc failure
When dma_fence_chain_alloc() fails, properly release the user fence
reference to prevent a memory leak.
(cherry picked from commit a5d5634cde48a9fcd68c8504aa07f89f175074a0)
A flaw was found in the Linux kernel, specifically within the drm/xe/sync component. When the dma_fence_chain_alloc() function fails, the user fence reference is not properly released, resulting in a memory leak. This issue could lead to system instability or denial of service.
Отчет
This Moderate impact memory leak in the drm/xe/sync component of the Linux kernel can lead to a denial of service. The flaw occurs when a user fence reference is not properly released upon dma_fence_chain_alloc() failure. Exploitation requires local access and low privileges, potentially causing system instability on affected Red Hat Enterprise Linux 9 and 10 systems.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
