CVE-2026-43153

In the Linux kernel, the following vulnerability has been resolved: xfs: remove xfsattrleafhasname The calling convention of xfsattrleafhasname is problematic, because it returns a NULL buffer when xfsattr3leafread fails, a valid buffer when xfsattr3leaflookupint returns -ENOATTR or -EEXIST, and ...

CVE-2025-71295

In the Linux kernel, the following vulnerability has been resolved: fs/buffer: add alert in trytofreebuffers for folios without buffers trytofreebuffers can be called on folios with no buffers attached when filemapreleasefolio is invoked on a folio belonging to a mapping with ASRELEASEALWAYS set...

CVE-2025-71292

CVE-2025-71292 concerns the Linux kernel’s JFS rename path. The issue is an nlink overflow when renaming a child directory inside a directory whose nlink is at its maximum (-1). In this edge case, nlink is first incremented and then decremented, which wraps to 0 and triggers a drop_nlink warning....

CVE-2025-71292 jfs: nlink overflow in jfs_rename

In the Linux kernel, the following vulnerability has been resolved: jfs: nlink overflow in jfsrename If nlink is maximal for a directory -1 and inside that directory you perform a rename for some child directory not moving from the parent, then the nlink of the first directory is first incremente...

CVE-2026-43262

CVE-2026-43262 stems from a Linux kernel gfs2 fiemap page fault: gfs2_fiemap() calls iomap_fiemap() while holding the inode glock, risking recursive glock taking if the fiemap buffer maps to the same inode. The fix disables page faults for iomap_fiemap() and faults in the buffer by hand when need...

CVE-2026-43249 9p/xen: protect xen_9pfs_front_free against concurrent calls

In the Linux kernel, the following vulnerability has been resolved: 9p/xen: protect xen9pfsfrontfree against concurrent calls The xenwatch thread can race with other back-end change notifications and call xen9pfsfrontfree twice, hitting the observed general protection fault due to a double-free...

CVE-2026-43249

The CVE-2026-43249 entry describes a race in the Linux kernel 9p/xen frontend: xenwatch and backend change notifications can concurrently call xen_9pfs_front_free, causing a double-free and a general protection fault. The fixes guard the teardown path so only a single caller releases the front-en...

CVE-2026-43228

In the Linux kernel, the following vulnerability has been resolved: hfs: Replace BUGON with error handling for CNID count checks In a06ec283e125 nextid, foldercount, and filecount in the super block info were expanded to 64 bits, and BUGONs were added to detect overflow. This triggered an error...

CVE-2026-43209

CVE-2026-43209 – minix filesystem sanity check in Linux kernel : The minix filesystem implementation lacked proper sanity checks in minix_check_superblock(), notably for s_log_zone_size, which the patch now enforces (only 0 is supported). The update also adds sanity checks for other superblock fi...

In the Linux kernel, the following vulnerability has been resolved: xfs: delete attr leaf freemap entries when empty Back in commit 2a2b5932db6758 "xfs: fix attr leaf header freemap.size underflow", Brian Foster observed that it's possible for a small freemap at the end of the end of the xattr...

CVE-2026-43181 gpio: sysfs: fix chip removal with GPIOs exported over sysfs

In the Linux kernel, the following vulnerability has been resolved: gpio: sysfs: fix chip removal with GPIOs exported over sysfs Currently if we export a GPIO over sysfs and unbind the parent GPIO controller, the exported attribute will remain under /sys/class/gpio because once we remove the pare...

CVE-2026-43179 erofs: fix incorrect early exits for invalid metabox-enabled images

In the Linux kernel, the following vulnerability has been resolved: erofs: fix incorrect early exits for invalid metabox-enabled images Crafted EROFS images with metadata compression enabled can trigger incorrect early returns, leading to folio reference leaks. However, this does not cause system...

CVE-2026-43178

In the Linux kernel, the procfs component has a vulnerability in do_procmap_query() that can trigger a double mmput() of an mm_struct when a user passes an incorrectly sized buffer for PROCMAP_QUERY's build ID. The root cause is a change that defers cleanup after unlocking mmap_lock and per-VMA, ...
