kernel: IGB driver inadequate buffer size for frames larger than MTU

A flaw was found in igbconfigurerxring in drivers/net/ethernet/intel/igb/igbmain.c in the IGB driver in the Linux kernel. An overflow of the contents from a packet that is too large will overflow into the kernel's ring buffer, leading to a system integrity issue...

kernel: NULL pointer dereference in can_rcv_filter

A NULL pointer dereference issue was found in the can protocol in net/can/afcan.c in the Linux kernel, where mlpriv may not be initialized in the receive path of CAN frames. This flaw allows a local user to crash the system or cause a denial of service...

kernel: use after free in unix_stream_sendpage

A use-after-free flaw was found in the Linux kernel's afunix component that allows local privilege escalation. The unixstreamsendpage function tries to add data to the last skb in the peer's recv queue without locking the queue. This issue leads to a race condition where the unixstreamsendpage...
