kernel: ovl: fix use after free in struct ovl_aio_req
A use-after-free flaw was found in the Linux kernel’s Ext4 File System in how a user triggers several file operations simultaneously with the overlay FS usage. This flaw allows a local user to crash or potentially escalate their privileges on the system. Only if patch 9a2544037600 "ovl: fix use...
Important: kernel
Issue Overview: A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol L2TP. A missing lock when clearing skuserdata can lead to a race condition and NULL pointer dereference. A local user could use this flaw to potentially crash the system causing a denial of service. CVE-2022-4129 In...
The vulnerability of the ovl_copy_up_one() function in the fs/overlayfs/copy_up.c file of the OverlayFS file system in the Linux operating system allows a hacker to gain increased privileges.
The vulnerability of the ovlcopyupone function in the fs/overlayfs/copyup.c file of the OverlayFS file system in the Linux operating system is related to incorrect handling of stuid and stgid. Exploiting this vulnerability can allow an attacker to increase their privileges...

It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory in some situations, leading to an out-of- bounds write vulnerability. An attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2023-3090 Sh...
CVE-2023-2640
On Ubuntu kernels carrying both c914c0e27eb0 and "UBUNTU: SAUCE: overlayfs: Skip permission checking for trusted.overlayfs. xattrs", an unprivileged user may set privileged extended attributes on the mounted files, leading them to be set on the upper files without the appropriate security checks...
USN-6221-1 linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities
It was discovered that a race condition existed in the overlay file system implementation in the Linux kernel. A local attacker could use this to cause a denial of service system crash. CVE-2021-20321 It was discovered that the virtual terminal vt device implementation in the Linux kernel contain...
