FFS - F File System This is a cli tool for searching files like grep that does not use the OS kernel to read files, but reads your disks directly. It is practically useless, but insanely cool. this is just 1.5k lines of C code that: requires sudo only when reading a raw device node e.g. /dev/rdis...

btrfsfixes: Custom BTRFS Repair Tools Custom tools written during recovery of a 12TB multi-device BTRFS pool with severe extent tree corruption that the native commands btrfs check --repair, --init-extent-tree, etc. could not repair. SeeINCIDENT-ANALYSIS.md for a structured case study of the...

CVE-2026-90261

A flaw was found in the btrfs zoned filesystem component of the Linux kernel. During metadata-heavy operations, a specific writeback scenario can prevent the system from properly managing active block groups. This issue can lead to a transaction abortion, forcing the filesystem into a read-only...

CVE-2026-90262

A flaw was found in the Linux kernel's btrfs filesystem. This flaw occurs when the btrfsreadmerkletreepage function encounters a Merkle folio that is not up-to-date. Instead of retrying the read, the system incorrectly treats this as a permanent error, causing transient read failures to become...

CVE-2026-90260

A flaw was found in the Linux kernel's Btrfs zoned filesystem. When a freed-but-still-dirty tree block is written out as zeros, the btreecsumonebio function improperly clears the extent buffer's in-memory content. This can lead to corruption of the extent tree, potentially causing system...

CVE-2026-90259

A flaw was found in btrfs qgroup. An incorrect length calculation in the qgroupfreereserveddata function can lead to a much larger length being used than intended. This error in calculation may result in improper data handling, potentially causing system instability or data corruption...

CVE-2026-90263

A flaw was found in the Linux kernel's btrfs filesystem. A local user could bypass the intended read-only protection by setting a POSIX Access Control List ACL on a btrfs filesystem configured as read-only. This vulnerability occurs because the setacl code path fails to properly check the...

ROS-20261013-73-0060

The vulnerability of the fs/btrfs/qgroup.c component in the Linux operating system is related to deficiencies in handling error situations. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2026-98245

A flaw was found in the Linux kernel's Btrfs file system. A local user could exploit this vulnerability to cause a Denial of Service DoS or potentially escalate privileges. The issue occurs due to missing synchronization during device replacement operations, where a concurrent transaction commit...

CVE-2026-98244

A flaw was found in the Linux kernel's Btrfs file system. When an error occurs while rebuilding the free space tree, the kernel fails to properly reset an internal state flag on failure paths. A local user could exploit this condition during filesystem operations, leaving the flag set on an activ...

CVE-2026-98279

A flaw was found in the Linux kernel's Btrfs file system. A local user can cause a denial of service DoS by enabling file verification fsverity on a subvolume that exceeds its quota or storage space limits. When the operation fails due to insufficient space, the clean-up process fails to acquire...

CVE-2026-98269

A flaw was found in the Linux kernel's Btrfs file system. When operations such as hole punching or file cloning encounter an error while updating file metadata, the kernel does not abort the active transaction. A local user could trigger these operations, potentially causing partially updated fil...

ROS-20261009-73-0536

The vulnerability of the btrfs/inode.c component in the Linux operating system’s kernel is related to the allocation of unlimited memory. Exploiting this vulnerability can allow an attacker to cause a service failure...
