CVE-2026-23018

CVE-2026-23018 describes a Linux kernel vulnerability in the btrfs code path. In btrfs_read_locked_inode(), a path with a read-locked leaf from a subvolume tree is used while calling btrfs_init_file_extent_tree(), which may perform GFP_KERNEL allocations and trigger memory reclaim. This can creat...

CVE-2025-71184

CVE-2025-71184 affects the Linux kernel’s btrfs subsystem. The issue is a NULL dereference in btrfs_evict_inode() when tracing inode eviction because the root may be NULL. The fix ensures root is treated as 0 or delays tracing until the root is non-NULL, preventing a NULL dereference during evict...

CVE-2025-71183

In the Linux kernel, the following vulnerability has been resolved: btrfs: always detect conflicting inodes when logging inode refs After rename exchanging either with the rename exchange operation or regular renames in multiple non-atomic steps two inodes and at least one of them is a directory,...

CVE-2025-71183

CVE-2025-71183 affects the Linux kernel via the btrfs filesystem. The issue arises during rename exchanges (or multi-step renames) where two inodes, one a directory, can produce a log containing only some inodes. During replay, this can lead to deleting an inode that should not be deleted after a...
