PT-2024-32749

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.58 Description The issue is related to an out-of-bounds access in the ext4 filesystem when system.data xattr changes underneath the filesystem. This can lead to a use-after-free error detected by KASAN. The...

CVE-2024-42305

CVE-2024-42305 affects the Linux kernel ext4, where a dir-indexing edge case could trigger out-of-bounds access during directory entry splitting when the first two entries are not dot/dotdot. The description and connected material explain that make_indexed_dir() assumed the first two dirents are ...
