CVE-2026-43118
A flaw was found in the Linux kernel's Btrfs filesystem. When a file is truncated to zero size and then a hardlink is created, a power failure followed by log replay can cause the file to incorrectly retain its original size instead of being zero. This data integrity issue may lead to unexpected...
CVE-2026-43117
In the Linux kernel, the following vulnerability has been resolved: btrfs: tracepoints: get correct superblock from dentry in event btrfssyncfile If overlay is used on top of btrfs, dentry-dsb translates to overlay's super block and fsid assignment will lead to a crash. Use fileinodefile-isb to...

A flaw was discovered in btrfsgetrootref in fs/btrfs/disk-io.c within the btrfs filesystem of the Linux kernel, due to a double decrement of the reference count. This issue may allow a local attacker with user privileges to crash the system or may lead to the leakage of internal kernel informatio...
CVE-2026-43046
A flaw was found in the Linux kernel's btrfs filesystem. This vulnerability allows an attacker with local access to trigger a kernel bug system crash by providing specially crafted, malformed btrfs metadata on disk. Specifically, an invalid state where dropprogress.objectid is non-zero and...

CVE-2026-31519
A flaw was found in the Linux kernel's Btrfs filesystem. A race condition, a situation where the outcome depends on the sequence or timing of uncontrollable events, can occur during the creation and cleanup of subvolumes. This can result in a valid subvolume being incorrectly marked as a broken...
CVE-2026-31434
A flaw was found in the Linux kernel's btrfs filesystem. When sub-groups for space information are created, associated kobject names are allocated. However, these names are not properly released when the sub-groups are removed, leading to a memory leak. A local user could exploit this vulnerabili...
