1. 漏洞描述

The Linux Kernel, the operating system core itself.

Security Fix(es):

In the Linux kernel before 6.4.5, drivers/gpu/drm/drm_atomic.c has a use-after-free during a race condition between a nonblocking atomic commit and a driver unload.(CVE-2023-51043)

A use-after-free flaw was found in the Linux Kernel due to a race problem in the unix garbage collector's deletion of SKB races with unix_stream_read_generic() on the socket that the SKB is queued on.(CVE-2023-6531)

A Null pointer dereference problem was found in ida_free in lib/idr.c in the Linux Kernel. This issue may allow an attacker using this library to cause a denial of service problem due to a missing check at a function return.(CVE-2023-6915)
