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occurs because a pointer to network packet data is not updated after memory is reallocated, leading to the use of an outdated memory address.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...

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...

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: netfilter: ebtables SNAT target writes to shared memory pages during ARP hardware address rewrite

A flaw was found in the Linux kernel's netfilter bridge ebtables SNAT Source Network Address Translation module. This vulnerability allows a local attacker on a system configured with specific bridge netfilter rules to improperly modify underlying memory pages during an ARP Address Resolution...

CVE-2026-99216 Drivers: hv: Don't reset VMBus connection state on error/exit paths

In the Linux kernel, the following vulnerability has been resolved: Drivers: hv: Don't reset VMBus connection state on error/exit paths In two places, current code forces vmbusconnection.connstate to DISCONNECTED prior to calling vmbusdisconnect. But vmbusdisconnect calls vmbusinitiateunload, whi...

CVE-2026-99216

A flaw exists in the Linux kernel 's Hyper-V Virtual Machine Bus (VMBus ) driver. During driver exit or connection failure, the code prematurely sets vmbus_connection.conn_state to DISCONNECTED before calling vmbus_disconnect(). Because vmbus_disconnect() only unloads the connection if the state ...

CVE-2026-99215

The Linux kernel contains a use-after-free vulnerability in the power supply core. The issue arises because a power supply's callbacks (such as external_power_changed()) can fire immediately upon registration. If a power supply is unregistered while a callback is still executing, the driver data ...

CVE-2026-99214

The Linux kernel contains a vulnerability in the drm/vc4 driver related to HDMI output. A race condition exists where audio can be triggered by the HPD handler and begin startup before video is fully restored. This leads to a call to vc4_hdmi_write_infoframe() while Packet RAM is disabled, as the...
