kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...

CVE-2026-80519

A flaw was found in the Linux kernel. Specifically, within the OpenVPN OVPN module's crypto completion callback mechanism, a timing issue exists. This vulnerability arises when peer references are released prematurely, before the associated cleanup operations are complete. An attacker could...

CVE-2026-63381

A flaw was found in Libevent, an event notification library. A use-after-free vulnerability exists in the evbufferaddbufferreference function when it processes an output buffer with a zero length. This can lead to a dangling pointer, which an attacker could exploit to cause memory corruption or...

CVE-2026-80563

A flaw was found in the Linux kernel's gpio: sloppy-logic-analyzer component. A local attacker with root privileges can exploit a race condition during the unbinding of a platform device. This vulnerability allows writing into memory that has already been freed, which can lead to system instabili...

CVE-2026-74746

A flaw was found in the netfilter flowtable component of the Linux kernel. This vulnerability occurs due to a timing issue where the system's garbage collection can free a network flow while it is still being set up. This can lead to a 'use-after-free' condition, where the system attempts to acce...

CVE-2026-80572

A flaw was found in the Linux kernel's byd input driver. A race condition exists during device disconnection where the byddisconnect function frees private data before ensuring that a timer callback, bydcleartouch, has completed. This can lead to the callback attempting to access memory after it...
