K000162740: Linux kernel vulnerability CVE-2026-63803

Security Advisory Description In the Linux kernel, the following vulnerability has been resolved: hdlcppp: sync per-proto timers before freeing hdlc state Each PPP control protocol LCP/IPCP/IPV6CP embedded in struct ppp registers a timer via timersetup. That struct ppp is the hdlc-state allocatio...

CVE-2026-63803

A flaw was found in the Linux kernel's hdlcppp module. This use-after-free vulnerability occurs because the Point-to-Point Protocol PPP control timers are not properly synchronized before the associated memory is freed. An attacker could potentially exploit this by triggering a race condition,...
