In the Linux kernel, the following vulnerability has been resolved: gfs2: Fixed possible data races in gfs2showoptions Some fields such as gtlogdsecs of the struct gfs2tune are accessed without holding the lock gtspin in gfs2showoptions: val = sdp-sdtune.gtlogdsecs; if val != 30 seqprintfs,...

CVE-2026-71222

A heap out-of-bounds read vulnerability was found in gfs2-utils. The eanumptrs field from on-disk extended attribute metadata is consumed without bounds validation, causing a heap buffer over-read that may disclose sensitive memory contents or cause a crash when processing crafted GFS2 filesystem...

CVE-2026-71219

A stack overflow vulnerability was found in gfs2-utils. The hash table traversal code in metawalk.c uses alloca with an exponentially-derived size from the untrusted on-disk didepth field without bounds validation. A crafted GFS2 filesystem image with a large didepth value causes stack exhaustion...

UBUNTU-CVE-2026-71221

A stack out-of-bounds write vulnerability was found in gfs2-utils. In savemeta, the height value from on-disk inode metadata is used as a loop bound without bounds checking, causing a stack buffer overflow that may lead to arbitrary code execution when processing crafted GFS2 filesystem images...

UBUNTU-CVE-2026-71224

A stack overflow vulnerability was found in gfs2-utils. The metadata walk code in metawalk.c uses alloca with an untrusted inode height value from on-disk metadata without bounds validation, causing stack exhaustion and a denial of service when processing crafted GFS2 filesystem images...

kernel: gfs2: Fix use-after-free in iomap inline data write path

A flaw was found in the Linux kernel's GFS2 filesystem. This memory corruption vulnerability, a use-after-free, occurs in the iomap inline data write path. The issue arises because a data buffer is released prematurely while still being referenced, leading to a write to freed memory. This could...
