CVE-2026-53360

The CVE-2026-53360 entry concerns a Linux kernel KVM/SEV issue: if GHCB v2+ is used, in-GHCB scratch area must reside in the shared buffer. The root cause is a bounds check flaw in snp_begin_psc() where idx_end is validated against VMGEXIT_PSC_MAX_COUNT (253) but not against the actual buffer siz...

CVE-2026-45929

A flaw was found in the Linux kernel's ovpn module. A use-after-free vulnerability exists in the ovpnnetxmit function where a freed skb socket buffer pointer can be used for subsequent operations. This can occur when skbsharecheck frees the original skb if it is shared, leading to a stale pointer...
