CVE-2026-90260

CVE-2026-90260 is a btrfs zoned filesystem vulnerability in the Linux kernel . The root cause is that btree_csum_one_bio() memzeroed the extent buffer's own folios before submission to advance the zone write pointer, destroying in-memory data while it was still referenced. When btrfs_free_tree_bl...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability arises from the destruction of the extent buffer in memory when clearing tree blocks that have been released but are still dirty on a zoned file system. This buffer may still be referenced, causing subsequent operations to read the...
