CVE-2026-72258

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture System on Chip ASoC Mediatek MT8183 audio driver. The Audio Front End AFE probe assigns reserved memory but does not release it when the driver is removed or if probe failures occur. This oversight can lead to a memory leak,...

CVE-2026-72256

A flaw was found in the Linux kernel. The xtcluster module, specifically within the xtclustermt function, incorrectly processes template connection tracking conntrack objects. This state confusion occurs when a template conntrack is attached before it is fully initialized, leading to xtclusterhas...

CVE-2026-72255

A flaw was found in the Linux kernel's netfilter component, specifically within the nfqueue functionality. When a bridged packet is queued to NFQUEUE, it can retain a reference to a bridge's private fake destination 'dst' even after the bridge teardown has begun. This can lead to a use-after-free...

CVE-2026-72253

A flaw was found in the Linux kernel's Netfilter Session Initiation Protocol SIP connection tracking helper. This vulnerability occurs when network traffic control tc ingress or Open vSwitch openvswitch subsystems are active, and a specific media handling feature sipexternalmedia is enabled. The...

CVE-2026-72252

A flaw was found in the Linux kernel. A memory allocation failure during network filter operations can lead to an inconsistent state within the netfilter: nftsetpipapo module. This inconsistency can result in out-of-bounds writes, which may allow a local attacker to cause a system crash denial of...

CVE-2026-72250

A flaw was found in the Linux kernel's nfconntrackreasm module, specifically within the IPv6 defragmentation process. An attacker could exploit this by sending specially crafted IPv6 fragmented packets. The nfctfrag6reasm function incorrectly adjusts the macheader offset, causing the system to...

CVE-2026-72249

A flaw was found in the Linux kernel's netfilter flowtable.
