CVE-2026-46002

The CVE affects the Linux kernel ext2 filesystem handling of inodes with i_nlink == 0 and a non-zero i_mode with zero i_dtime. A crafted image could present such an inode to the VFS, triggering WARN_ON in drop_nlink() via ext2_unlink(), ext2_rename(), and ext2_rmdir(). The fix extends the existin...

CVE-2026-45983

The CVE-2026-45983 entry describes a Linux kernel nfsd issue where during v4 request compound arg decoding, idmap upcalls can be delayed, causing cache_check() to defer and drop requests. This prevents nfs4svc_encode_compoundres from running and leaves NFSD4_SLOT_INUSE set, causing subsequent SEQ...

CVE-2026-45942

Summary of CVE-2026-45942 : A race condition in the Linux kernel ext4 bitmap handling enables inconsistent bitmap reporting due to concurrent page migration and bitmap modification in the load_buddy path.

CVE-2026-45915

In CVE-2026-45915, the Linux kernel FAT filesystem code fixes a parent-link underflow in rmdir. A corrupted FAT image could leave a directory inode with an incorrect i_nlink, causing rmdir to call drop_nlink(dir) and drive i_nlink to 0, triggering a WARN_ON. The patch adds a sanity check in vfat_...
