The vulnerability of the scrub_submit_initial_read() function in the file system of the brtfs kernel of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the scrubsubmitinitialread function in the fs/btrfs/scrub.c file of the Linux operating system’s file system brtfs relates to the use of memory after it is freed. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...

CVE-2021-47145

In the Linux kernel, the following vulnerability has been resolved: btrfs: do not BUGON in linktofixupdir While doing error injection testing I got the following panic kernel BUG at fs/btrfs/tree-log.c:1862! invalid opcode: 0000 1 SMP NOPTI CPU: 1 PID: 7836 Comm: mount Not tainted 5.13.0-rc1+ 305...

CVE-2021-47145

CVE-2021-47145 affects the Linux kernel (btrfs) where a BUG_ON in link_to_fixup_dir can trigger a kernel panic during error paths in log recovery. The description shows a replay/recover flow (replay_one_buffer, btrfs_recover_log_trees, open_ctree) panicking with an invalid opcode in fs/btrfs/tree...

CVE-2019-19036

A NULL pointer dereference flaw in the btrfsrootnode in fs/btrfs/ctree.c may occur if the rcudereference function return is not validated in time of failure. This flaw could allow an attacker to crash the system or leak internal kernel information. Mitigation Mitigation for this issue is either n...

Null pointer dereference

fs/btrfs/volumes.c in the Linux kernel before 5.1 allows a btrfsverifydevextents NULL pointer dereference via a crafted btrfs image because fsdevices-devices is mishandled within finddevice, aka CID-09ba3bc9dd15...

CVE-2018-14611

An issue was discovered in the Linux kernel through 4.17.10. There is a use-after-free in trymergefreespace when mounting a crafted btrfs image, because of a lack of chunk type flag checks in btrfscheckchunkvalid in fs/btrfs/volumes.c...
