vendor Linux Linux patch: 6.16

A flaw was found in the Linux kernel's Asynchronous Transfer Mode (ATM) subsystem. An authenticated local attacker could exploit a Use-After-Free (UAF) vulnerability in the /proc/net/atm/lec handling. This flaw occurs due to improper dev_put() calls without prior dev_hold() calls, leading to an imbalance in reference counting. Successful exploitation could allow the attacker to achieve privilege escalation or cause a denial of service.
