CVE-2026-13478 Out-of-bounds read in Zephyr ext2 block-bitmap validation from a crafted s_blocks_count

The Zephyr ext2 filesystem driver validates the on-disk block bitmap in ext2initfs subsys/fs/ext2/ext2impl.c by passing fsblocks = sblockscount - sfirstdatablock to ext2bitmapcountset. That helper subsys/fs/ext2/ext2bitmap.c treats its argument as a number of bits and reads one bitmap byte per...

ROS-20260629-73-0044

The vulnerability of the ext4validateblockbitmap function in the fs/ext4/balloc.c module of the Ext4 file system in the Linux operating system is related to the lack of validation for resource format correctness. Exploiting this vulnerability could allow an attacker to trigger a service failure...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: In ext4, the order of execution of functions ext4percpuparaminit and ext4mbinit has been changed. When running kvm-xfstests -c ext4/1k -C 1 generic/383 with the DOUBLECHECK macro defined, a panic occurs as follows:...

CVE-2026-43288

Summary: CVE-2026-43288 relates to the Linux kernel ext4 filesystem. The root cause is a per-CPU counter accessed before it is initialized during block bitmap validation, which can cause a kernel panic and potential DoS when mounting a specially crafted ext4 filesystem with quota/project options....
