CVE-2024-35784 btrfs: fix deadlock with fiemap and extent locking

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix deadlock with fiemap and extent locking While working on the patchset to remove extent locking I got a lockdep splat with fiemap and pagefaulting with my new extent lock replacement lock. This deadlock exists with our...

CVE-2024-35784

The CVE-2024-35784 entry concerns the Linux kernel: btrfs deadlock during fiemap/extent locking. Root cause: the extent lock was held for the entire fiemap traversal, risking pagefaults and deadlocks when fiemap data is copied to user space (mkwrite during mmap). Impact: potential deadlock in fil...

USN-6766-2: Linux kernel vulnerabilities

It was discovered that the Open vSwitch implementation in the Linux kernel could overflow its stack during recursive action operations under certain conditions. A local attacker could use this to cause a denial of service system crash. CVE-2024-1151 Sander Wiebing, Alvise de Faveri Tron, Herbert...

The vulnerability of the create_snapshot() function in the fs/btrfs/ioctl.c file of the file system in the Linux kernel allows a hacker to cause a service failure.

The vulnerability of the createsnapshot function in the fs/btrfs/ioctl.c file of the btrfs file system in Linux kernels is related to the lack of integrity checking after disk removal. Exploiting this vulnerability could allow an attacker to cause a service failure...

The vulnerability of the `btrfs_use_block_rsv()` function in the `fs/btrfs/block-rsv.c` file of the Linux kernel’s file system allows a malicious actor to cause a service failure.

The vulnerability of the btrfsuseblockrsv function in the fs/btrfs/block-rsv.c file of the btrfs file system in the Linux kernel is related to concurrent resource access race condition. Exploiting this vulnerability could allow a attacker to cause service failures...
