1. CVE-2026-71224 Gfs2-utils: gfs2-utils: stack overflow via alloca(i_height) in metadata walk

   Published 2026-09-03

   Medium·CVSS 4.7 EPSS 0.14%

   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 filesyste...

2. CVE-2026-71222 Gfs2-utils: gfs2-utils: heap out-of-bounds read via unchecked ea_num_ptrs in extended attribute processing

   Published 2026-09-03

   Medium·CVSS 6.3 EPSS 0.11%

   A heap out-of-bounds read vulnerability was found in gfs2-utils. The ea_num_ptrs 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 craf...

3. CVE-2026-71221 Gfs2-utils: gfs2-utils: stack out-of-bounds write via unchecked height in savemeta

   Published 2026-09-03

   High·CVSS 7.0 EPSS 0.13%

   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 fil...

4. CVE-2026-71220 Gfs2-utils: gfs2-utils: stack out-of-bounds write via unchecked di_height in gfs2_edit

   Published 2026-09-03

   High·CVSS 7.0 EPSS 0.13%

   A stack out-of-bounds write vulnerability was found in gfs2-utils. In gfs2_edit, the di_height field from on-disk inode metadata is used as an array index without bounds checking, causing a stack buffer overflow that may lead to arbitrary code execution when processing crafted GF...

5. CVE-2026-71219 Gfs2-utils: gfs2-utils: stack overflow via alloca(1<<di_depth) in hash table traversal

   Published 2026-09-03

   Medium·CVSS 4.7 EPSS 0.11%

   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 di_depth field without bounds validation. A crafted GFS2 filesystem image with a large di_depth value ca...
