CVE-2026-53151

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix the ACK parser to extract the SACK table for parsing Fix modification of the received skbuff in rxrpcinputsoftacks and a potential incorrect access of the buffer in a fragmented UDP packet the packet would probably hav...

CVE-2026-53151

CVE-2026-53151 concerns the Linux kernel AF_RXRPC subsystem, where legacy parsing of the SACK table could trigger an invalid buffer access when processing fragmented UDP packets. The fix updates rxrpc_input_soft_acks() and rxrpc_input_ack() logic so that SACK contents are not copied into a flat b...

CVE-2026-52912

A flaw was found in the Linux kernel's netfilter component. This vulnerability occurs because a queued bridge packet can retain a freed bridge master in its skb-dev field until it is reinjected. When the packet is later reinjected, the system attempts to use the freed bridge master, leading to a...
