CVE-2026-72379 fs: refuse O_TMPFILE creation with an unmapped fsuid or fsgid

In the Linux kernel, the following vulnerability has been resolved: fs: refuse OTMPFILE creation with an unmapped fsuid or fsgid vfstmpfile never checked that the caller's fsuid and fsgid map into the filesystem. On an idmapped mount whose idmapping does not cover the caller's fsu,gid, the -tmpfi...

CVE-2026-72379

The CVE-2026-72379 issue is in the Linux kernel: vfs_tmpfile() did not verify the caller’s fsuid/fsGid mappings, allowing O_TMPFILE creation on idmapped mounts when mapping does not cover the caller. The fix adds a missing fsuidgid_has_mapping() check so that O_TMPFILE creation is blocked unless ...

CVE-2026-72205

The CVE-2026-72205 entry concerns a Linux kernel ntfs mount failure leak: on fill_super error paths, vol-owned allocations (nls_map, volume_label) and lcn_empty_bits_per_page were not freed, leading to per‑mount leaks until module unload. The issue affects ntfs_fill_super() and err_out_now paths,...

CVE-2026-72196

CVE-2026-72196 involves the Linux kernel ntfs3 code where log_replay analysis could write past the dp->page_lcns[] array. The root cause: after find_dp() validates only the first cluster, the code loops over lrh->lcns_follow and writes dp->page_lcns[j + i] without bounding i by dp->lc...
