kernel: ipvlan: out-of-bounds write caused by unclear skb->cb

A flaw was found in the IPVLAN network driver in the Linux kernel. This issue is caused by missing skb-cb initialization in ipoptionsecho and can lead to an out-of-bounds write stack overflow. This may allow a local user to cause a denial of service or potentially achieve local privilege escalati...

kernel: remote DoS in TIPC kernel module

A remote denial of service vulnerability was found in the Linux kernel’s TIPC kernel module. The while loop in tipclinkxmit hits an unknown state while attempting to parse SKBs, which are not in the queue. Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization...

kernel: can: etas_es58x: es58x_rx_err_msg(): fix memory leak in error path

In the Linux kernel, the following vulnerability has been resolved: can: etases58x: es58xrxerrmsg: fix memory leak in error path In es58xrxerrmsg, if can-dosetmode fails, the function directly returns without calling netifrxskb. This means that the skb previously allocated by alloccanerrskb is no...
