NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug-devel-matched package and not the kernel-rt-debug-devel-matched package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

erofs: validate the extent length for uncompressed pclusters

syzkaller reported a KASAN use-after-free: https://syzkaller.appspot.com/bug?extid=2ae90e873e97f1faf6f2

The referenced fuzzed image actually has two issues:

  • m_pa == 0 as a non-inlined pcluster;
  • The logical length is longer than its physical length.

The first issue has already been addressed. This patch addresses the second issue by checking the extent length validity.
