CVE-2023-54281

CVE-2023-54281 (Linux kernel, btrfs) : The issue affects the btrfs inode lookup path during ino_lookup ioctl. When ino_lookup triggers btrfs_iget() to obtain an inode reference while holding the root btree, it may need to acquire an additional lock on the same/btrfs root path, risking a deadlock ...

CVE-2023-54253

The CVE describes a Linux kernel bug in Btrfs relocation: calling set_page_extent_mapped before validating the folio/page can trigger a kernel BUG during relocate_one_page. The fix, as noted in the description, is to move set_page_extent_mapped to after the btrfs_read_folio block so the subpage b...

CVE-2023-54224

CVE-2023-54224 concerns a Linux kernel issue in the btrfs subsystem where a deadlock could occur while running delayed items. Specifically, when inserting delayed items, a path may be returned with locked extent buffers, and the code later releases the delayed node (requiring the same mutex), cre...

CVE-2023-54185

CVE-2023-54185: Linux kernel btrfs fix fixes a bug in add_new_free_space() by removing BUG_ON() checks and returning errors instead, while optionally reporting the total newly added free space. This change ensures callers already handle errors without kernel panics or brittle aborts when in-memor...
