CVE-2026-58403

Hugo is a static site generator. From v0.123.0 through v0.163.0, Hugo's virtual filesystem is designed so that files under a mount cannot reach outside the mount tree, but a regression caused RootMappingFs.statRoot to call Stat, which follows symlinks, instead of Lstat, so a direct os.ReadFile...

SUSE CVE-2026-53341

In the Linux kernel, the following vulnerability has been resolved: fhandle: fix UAF due to unlocked -mntns read in maydecodefh maydecodefh accesses mount::mntns without holding any locks; that means the mount can concurrently be unmounted, and the mntnamespace can concurrently be freed after an...

Linux Distros Unpatched Vulnerability : CVE-2026-53341

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - fhandle: fix UAF due to unlocked -mntns read in maydecodefh maydecodefh accesses mount::mntns without holding any locks; that means the mount can concurrently b...

CVE-2026-53341

A flaw was found in the Linux kernel. This vulnerability, a Use-After-Free UAF, occurs in the fhandle component when the maydecodefh function accesses mount namespace information without proper locking. This creates a race condition that could be exploited by an attacker. The most severe...

CVE-2026-6682

In FatFS R0.16 and earlier contains a FAT32 integer overflow bug in mountvolume where fasize = fs-nfats can wrap, leading to attacker-controlled file-size metadata and unsafe read lengths in downstream callers. This maps to CWE-190 Integer Overflow or Wraparound. Estimated CVSS v3.1 vector:...

CVE-2026-6684

FatFs prior to R0.16 that use GPT scanning with 'FFLBA64 = 1' contains an issue where an unbounded loop count derived from GPT header field GPTHPtNum, enabling extremely long or effectively infinite mount-time scans. This maps to CWE-835 Loop with Unreachable Exit Condition. Estimated CVSS v3.1...

CVE-2026-6684

CVE-2026-6684 affects FatFs prior to R0.16 when GPT scanning is used with FF_LBA64 = 1. The issue stems from an unbounded loop count derived from the GPT header field GPTH_PtNum, leading to extremely long or effectively infinite mount-time scans (CWE-835: Loop with Unreachable Exit Condition). Af...
