CVE-2026-45943

A flaw was found in the Linux kernel's erofs filesystem. This issue occurs when compressed folios for ztailpacking pclusters are not validated before being added to I/O chains. An attacker could potentially trigger a NULL pointer dereference, leading to a system crash and a Denial of Service DoS...

AZL-88632 CVE-2026-46078 affecting package kernel for versions less than 6.6.141.1-1

In the Linux kernel, the following vulnerability has been resolved: erofs: fix the out-of-bounds nameoff handling for trailing dirents Currently we already have boundary-checks for nameoffs, but the trailing dirents are special since the namelens are calculated with strnlen with unchecked nameoff...

AZL-88745 CVE-2026-45999 affecting package kernel for versions less than 6.6.141.1-1

In the Linux kernel, the following vulnerability has been resolved: erofs: fix unsigned underflow in zerofslz4handleoverlap Some crafted images can have illegal !partialdecoding && mllen out access reads past the decompressedpages array. However, such crafted cases can correctly result in a...

CVE-2026-45943 erofs: fix inline data read failure for ztailpacking pclusters

In the Linux kernel, the following vulnerability has been resolved: erofs: fix inline data read failure for ztailpacking pclusters Compressed folios for ztailpacking pclusters must be valid before adding these pclusters to I/O chains. Otherwise, zerofsdecompresspcluster may assume they are alread...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: erofs: Avoid infinite loops caused by corrupted subpage compact indexes. Robert reported an infinite loop observed in two crafted images. The root cause is that clusterofs can be larger than lclustersize for !NONHEAD lclusters...

CVE-2026-43179

A flaw was found in the Linux kernel's EROFS filesystem. An attacker could provide a specially crafted EROFS image with metadata compression enabled. This could trigger incorrect early returns within the kernel, leading to folio reference leaks. While this issue does not cause system crashes or...

CVE-2026-43154

A flaw was found in the Linux kernel's EROFS filesystem. Crafted EROFS images containing valid volume labels can trigger incorrect early returns during volume label handling, leading to folio reference leaks. This issue could potentially lead to minor resource exhaustion, but it does not cause...

CVE-2026-43166

In the Linux kernel, the following vulnerability has been resolved: erofs: fix interlaced plain identification for encoded extents Only plain data whose start position and on-disk physical length are both aligned to the block size should be classified as interlaced plain extents. Otherwise, it mu...

erofs: add GFP_NOIO in the bio completion if needed

...

CVE-2026-31514

A flaw was found in the Linux kernel's erofs filesystem component. When an input/output I/O request for a file-backed mount is interrupted by a SIGKILL signal, the system incorrectly marks unused data blocks as up-to-date. This can lead to data integrity issues or the potential disclosure of stal...

CVE-2026-31467

In the Linux kernel, the following vulnerability has been resolved: erofs: add GFPNOIO in the bio completion if needed The bio completion path in the process context e.g. dm-verity will directly call into decompression rather than trigger another workqueue context for minimal scheduling latencies...

kernel: Linux kernel erofs: Use-After-Free due to device type mismatch

A flaw was found in the Linux kernel's erofs filesystem. A local attacker could exploit a use-after-free UAF vulnerability by mounting an erofs filesystem with a specific configuration where the primary and extra devices have mismatched types. This improper handling of device initialization error...
