Linux kernel STM micro Ethernet driver Heap Buffer Overflow DoS

The vulnerability in the jumbofrm function within the drivers/net/ethernet/stmicro/stmmac/chainmode.c file of the Ethernet network adapter driver for the Linux kernel is related to an integer overflow. Exploitation of this vulnerability may allow a remote attacker to compromise the confidentialit...

CVE-2026-31649 net: stmmac: fix integer underflow in chain mode

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: fix integer underflow in chain mode The jumbofrm chain-mode implementation unconditionally computes len = nopagedlen - bmax; where nopagedlen = skbheadlenskb linear bytes only and bmax is BUFSIZE8KiB or BUFSIZE2KiB...
