kernel: packet: use consistent hard_header_len in non-ring send paths

An out-of-bounds write problem was observed in packetsendmsgspkt in net/packet/afpacket.c in the Linux Kernel. In this flaw, AFPACKET hardheaderlen race may allow local privilege escalation...

kernel: pppoe: reload header pointer after dev_hard_header()

A flaw was found in the Linux kernel's PPPoE Point-to-Point Protocol over Ethernet implementation. This vulnerability occurs because a pointer to network packet data is not updated after memory is reallocated, leading to the use of an outdated memory address. An attacker with local access could...

CVE-2026-99208

In the Linux kernel, the following vulnerability has been resolved: drm/xe/oa: Zero OA buffer at allocation ttmbotypekernel BOs are not guaranteed to be zeroed on allocation and may contain data from previously freed pages. Since the OA buffer is mmap'able by userspace, this can expose stale kern...

kernel: net: bridge: stop fast-leave after deleting a port group

A flaw was found in the Linux kernel's network bridge module. When handling multicast fast-leave, a vulnerability exists where the system may attempt to access a port group after it has been deleted. This can occur if multicast-to-unicast was previously enabled and then disabled, leading to a sta...
