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...

SUSE CVE-2026-98959

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix xattr replace when multiple xattrs are packed in the same item If we have a btrfsdiritem item that packs multiple xattrs and then we replace the value of one of them with the setxattr2 family of syscalls with another...

CVE-2026-99067

The Linux kernel contains a vulnerability in the btrfs filesystem related to the scrub functionality. Specifically, the scrub_print_warning_inode() function fails to drop the reference taken by btrfs_get_fs_root() when paths_from_inode() fails, causing a reference leak to the root every time path...

CVE-2026-98963

The Linux kernel contains a vulnerability in the btrfs filesystem. Specifically, if all bios finish before btrfs_encoded_read_regular_fill_pages() returns, the call to btrfs_uring_read_extent_endio() could result in a negative errno . This caused a double free and unlock issue because both btrfs_...

In the Linux kernel, the following vulnerability has been resolved: btrfs: always return -EIOCBQUEUED after btrfsuringreadextentendio If all bios finish before btrfsencodedreadregularfillpages returns, it calls btrfsuringreadextentendio and previously returned the I/O status. A negative errno the...

CVE-2026-98962

In the Linux kernel, the following vulnerability has been resolved: btrfs: free iov when btrfsuringreadextent fails After btrfsuringreadextent, the caller always jumped to outacct. That skips kfreedata-iov, which is only correct for -EIOCBQUEUED where the deferred path owns the iov. On failure,...

CVE-2026-98962

The Linux kernel contains a vulnerability within the btrfs file system. Specifically, after the btrfs_uring_read_extent() function is called, the code incorrectly jumped to out_acct, causing it to skip the kfree(data->iov) operation. This memory deallocation is only appropriate for the -EIOCBQ...
