UBUNTU-CVE-2026-72187

In the Linux kernel, the following vulnerability has been resolved: ntfs: avoid self-deadlock during inode eviction An attribute-list update performed while allocating clusters can drop the last reference to the temporary attribute inode. Evicting that inode drops its reference to the base inode...

CVE-2026-74363

The CVE-2026-74363 entry concerns a Linux kernel BPF/bpffs use-after-free related to inode cleanup. The root cause was that moved cleanup from ->free_inode() into ->destroy_inode() to avoid sleeping in RCU when calling bpf_any_put(), which inadvertently removed the RCU delay on freeing the ...

EUVD-2026-59506

In the Linux kernel, the following vulnerability has been resolved: configfslookup: don't leave -sdentry dangling on failure Normally -sdentry is cleared when dentry it's pointing to becomes negative on eviction, realistically. However, that only happens if dentry gets to be positive in the first...

CVE-2026-74359

In CVE-2026-74359, the Linux kernel fixes a use-after-free in configfs_lookup where a dangling ->s_dentry can be observed after inode allocation failure. The root cause was that, on certain failure paths, the dentry’s link to a configfs_dirent wasn’t cleared, leaving a pointer in ->s_dentry...

CVE-2026-74358 ext4: fix fast commit wait/wake bit mapping on 64-bit

In the Linux kernel, the following vulnerability has been resolved: ext4: fix fast commit wait/wake bit mapping on 64-bit On 64-bit, ext4 dynamic inode states live in the upper half of iflags, and ext4testinodestate applies the corresponding +32 offset. The fast-commit wait and wake paths...

CVE-2026-74350

CVE-2026-74350 describes a vulnerability in the Linux kernel OCFS2 fast symlink handling. If a zero-cluster fast symlink inode has an i_size that exceeds the inline payload capacity or its payload is not exactly NUL-terminated at i_size, a memcpy during read can read past the inode block buffer, ...
