CVE-2026-90264

CVE-2026-90264 is a race condition in the Linux kernel's btrfs filesystem that can cause a kernel BUG/panic . The bug occurs when a direct IO finishes short: the file's isize is reverted, which skips the ordered extent (OE) wait during subsequent buffered writeback. This allows a new OE to be ins...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: btrfs: fixed the qgroup reserve leaks in cowfilerange. In the buffered write path, the dirty page owns the qgroup reserve until it creates an orderedextent. Therefore, any errors that occur before the orderedextent is created...
