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...

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...

EUVD-2026-26645

In the Linux kernel, the following vulnerability has been resolved: btrfs: reject root items with dropprogress and zero droplevel BUG When recovering relocation at mount time, mergerelocroot and btrfsdropsnapshot both use BUGONlevel == 0 to guard against an impossible state: a non-zero dropprogre...

CVE-2026-31666

A flaw was found in the Linux kernel's btrfs filesystem. An incorrect return value in the lookupextentdataref function can lead to the system believing a lookup succeeded when it did not. This can cause operations to be performed on the wrong extent tree item, potentially resulting in data...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from an incorrect return value of the lookupextentdataref function in btrfs, potentially causing damag...

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...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the lack of setting BTRFSROOTORPHANCLEANUP when creating subvolumes. This could lead to orphan...
