A vulnerability in the ovldentryupdatereval function of the fs/overlayfs/copyup.c module of the Linux kernel file system is related to the use of memory after it has been freed. Exploitation of the vulnerability could allow an attacker to cause a denial of service...

Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-002135)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-002135 advisory. fs/overlayfs/copyup.c in the Linux kernel before 4.2.6 uses an incorrect cleanup code path, which allows local users to cause a denial of service dentry reference le...

The vulnerabilities of the functions ovl_encode_real_fh() (fs/overlayfs/copy_up.c) and show_mark_fhandle() (fs/notify/fdinfo.c) in the Linux operating system’s kernel allow a malicious actor to trigger a service failure.

The vulnerability of the functions ovlencoderealfh fs/overlayfs/copyup.c and showmarkfhandle fs/notify/fdinfo.c in the Linux kernel is related to the insufficient use of the assert function. Exploiting this vulnerability allows an attacker to cause a service failure...

The vulnerability of the `ovl_verify_area()` function in the `fs/overlayfs/copy_up.c` component of the Linux kernel allows a hacker to trigger a service failure.

The vulnerability of the ovlverifyarea function in the fs/overlayfs/copyup.c component of the Linux kernel is related to the insufficient use of the assert function. Exploiting this vulnerability could allow an attacker to cause a system failure...
