CVE-2026-23234

CVE-2026-23234 affects the Linux kernel F2FS subsystem. A use-after-free can occur in f2fs_write_end_io() due to a race with kill_f2fs_super freeing sbi before writeback complete, allowing access to freed sbi during page cache/inode cleanup. The published fix relocates the checkpoint thread wakeu...

CVE-2025-71105

In the Linux kernel, the following vulnerability has been resolved: f2fs: use global inlinexattrslab instead of per-sb slab cache As Hong Yun reported in mailing list: loop7: detected capacity change from 0 to 131072 ------------ cut here ------------ kmemcache of name 'f2fsxattrentry-7:7' alread...

CVE-2025-71105

CVE-2025-71105 documents a Linux kernel issue in f2fs where two slab caches (f2fs_xattr_entry-7:3 and f2fs_xattr_entry-7:7) with identical slab sizes cause kmem_cache_sanity_check warnings during mount operations. The root cause is using per-sb slab caches instead of a single global slab, leading...
