CVE-2026-68150

A flaw was found in the Linux kernel. A local attacker could trigger a double-unlock vulnerability in the filesystem's emergency thaw operation. This occurs when the sumount semaphore is released twice, leading to corruption of the semaphore's internal state. This corruption can cause system...

CVE-2026-68179

A flaw was found in the Linux kernel's Network Shared Memory NSM module. A local attacker can exploit an issue in the nsmdevioctl function where an incorrect mutex unlock operation is performed. This occurs when an initial data copy fails, leading to an attempt to unlock a mutex that was never...

CVE-2026-68245

A flaw was found in the drm/amdgpu component of the Linux kernel. A use-after-unlock vulnerability exists where a virtual machine VM pointer is dereferenced after its protective lock has been released. This allows the pointer to be modified, potentially leading to memory corruption. An attacker...

CVE-2026-68341

In the Linux kernel, the following vulnerability has been resolved: ovpn: fix use after free in unlockovpn unlockovpn iterates over the releaselist using llistforeachentry and drops the peer reference inside the loop body via ovpnpeerput. If this drops the last reference, the peer is eventually...

CVE-2026-68341

The CVE-2026-68341 issue affects the Linux kernel’s ovpn handling. In unlock_ovpn(), the code iterates a release_list with llist_for_each_entry() and drops peer references inside the loop via ovpn_peer_put(). If the last reference is dropped, the peer may be freed, but the loop’s advance uses pee...
