CVE-2026-80808

CVE-2026-80808 affects the Linux kernel ext4 filesystem. The bug is in ext4_xattr_block_set() , which retries indefinitely when an mbcache entry selected for reuse has a saturated reference count (≥ EXT4_XATTR_REFCOUNT_MAX , 1024). Normally this invariant holds because the count and MBE_REUSABLE_...

It's most useful for running semi-trusted code package installs, build scripts, CI jobs, unfamiliar repos with controlled side effects, and it can also compleme...

kernel: exfat: fix potential use-after-free in exfat_find_dir_entry()

A flaw was found in the Linux kernel's exFAT filesystem driver. A local attacker could exploit a use-after-free vulnerability in the exfatfinddirentry function. This occurs because a buffer is prematurely released while still being referenced, which can be triggered by processing a specially...
