CVE-2026-64074

The CVE-2026-64074 issue affects the Linux kernel, specifically a slab out-of-bounds write in statmount_mnt_idmap inside fs/statmount. When building a string with seq_printf(), an overflow may occur and manual increment of seq->count can push it to size+1, causing seq_has_overflowed() to miss ...

CVE-2026-64073

In the Linux kernel, the following vulnerability has been resolved: irqwork: Fix use-after-free in irqworksingle on PREEMPTRT On PREEMPTRT, non-HARD irqwork runs in per-CPU kthreads via runirqworkd, so irqworksync uses rcuwait to wait for BUSY==0. After irqworksingle clears BUSY via atomiccmpxchg...

CVE-2026-64072

The CVE-2026-64072 vulnerability affects the Linux kernel, specifically the NVMe I/O path. It describes a fix for a bio leak that occurred when an integrity mapping failed during mapping; the code could leak a local bio because it was treated as NULL. The root cause is that the kernel attempted t...

CVE-2026-64068

The CVE-2026-64068 issue affects the Linux kernel netfs subsystem, specifically a missing lock around retrying and adding subrequests (netfs_retry_read_subrequests() and netfs_retry_write_stream()) which could compromise integrity and availability. The vulnerability arises from not taking the app...

CVE-2026-64066

The CVE-2026-64066 entry describes a Linux kernel issue in the netfs component, specifically netfs_read_to_pagecache().
