CVE-2026-89602

A flaw was found in the erofs Enhanced Read-Only File System component of the Linux kernel. This vulnerability occurs when resizing global buffers, specifically if a resize operation fails after some buffers have already been enlarged. A subsequent retry can lead to memory corruption by attemptin...

CVE-2026-89602

In the Linux kernel, the following vulnerability has been resolved: erofs: skip sufficiently large global buffers when resizing zerofsgbufnrpages is advanced only after every global buffer has been grown. If a resize fails after some buffers were enlarged, a retry revisits those enlarged buffers...

CVE-2026-89602

CVE-2026-89602 affects the erofs filesystem driver in the Linux kernel . The flaw is in the global buffer resize path: z_erofs_gbuf_nrpages is advanced only after all buffers have been grown, so a retry after a partial resize failure revisits already-enlarged buffers. Retrying the same size cause...

CVE-2026-80899

CVE-2026-80899 affects the Linux kernel's EROFS filesystem fscache backend . The fscache subsystem introduced a hard dependency on netfs for a local filesystem and imposed a kernel-defined caching hierarchy considered inflexible compared to fanotify pre-content hooks. The feature had been depreca...
