CVE-2026-45953

A flaw was found in the Linux kernel's RAID5 module. When a low-level bitmap llbitmap bit state is unwritten in a degraded array, a missing check during write operations can cause the system to enter an infinite loop. This can lead to an I/O hang, effectively resulting in a Denial of Service DoS...

The vulnerability of the md_bitmap_read_sb() function in the drivers/md/md-bitmap.c file of the driver module exposes it to being exploited by attackers, causing service interruptions for systems supporting multiple devices such as RAID and LVM in the Linux kernel.

The vulnerability of the mdbitmapreadsb function in the drivers/md/md-bitmap.c file of the Linux support module for multiple devices RAID and LVM involves an operation that goes beyond the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to cause a service failure...
