kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...

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...

CVE-2026-80668

A flaw was found in the Netfilter subsystem of the Linux kernel, specifically within nfconntrackexpect. A race condition exists between the removal of an expectation and an expiring timer, which can allow the system to access a stale pointer. This vulnerability could lead to system instability or...

CVE-2026-80680

A flaw was found in the Linux kernel's i2c: amd-mp2 driver. During the registration of an I2C adapter, the driver may store a memory address pointer that later becomes invalid if the adapter registration fails. This can lead to the driver attempting to access this invalid memory location a "stale...

CVE-2026-80681

A flaw was found in the Linux kernel's vxlan component. A use-after-free vulnerability exists due to improper handling of the Ethernet header pointer after routeshortcircuit is called. When pskbmaypull reallocates the skb-head, the previously cached Ethernet header pointer becomes stale, leading ...
