Linux Distros Unpatched Vulnerability : CVE-2026-52791

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - fuse-overlayfs is an implementation of overlayfs in FUSE for rootless containers. Prior to 1.17, the release-1.x C branch preserves SUID and SGID mode bits in...

PT-2026-65846

fuse-overlayfs is an implementation of overlayfs in FUSE for rootless containers. Prior to 1.17, the release-1.x C branch preserves SUID and SGID mode bits in main.c during openO TRUNC and truncate handling on a copied-up file, allowing a low-privileged process to leave the upper-layer file with...

CVE-2026-64260

A flaw was found in the fuse-uring component of the Linux kernel. A race condition exists where the queue-stopped flag is not consistently checked under a lock. This can allow a struct fusereq to be prematurely freed while other operations are still in progress, potentially leading to memory...

CVE-2026-64265

A flaw was found in the Linux kernel's fuse component. When a fuse request is interrupted and then resent, a specific interrupt entry intrentry is not properly cleared. If the requesting task subsequently receives a fatal signal, this uncleared entry can lead to a use-after-free condition. This...

CVE-2026-64261

A flaw was found in the Linux kernel's fuse-uring component. This use-after-free vulnerability allows a local attacker to potentially achieve privilege escalation. The issue arises when the fuseuringasyncstopqueues function attempts to access memory that has already been freed, leading to...
