kernel: xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete

A flaw was found in the Linux kernel's xfrm IPSec framework subsystem. This vulnerability, a use-after-free, occurs when the system incorrectly manages memory related to security policies, specifically during the deletion of xfrmstate lists. An attacker with local access could exploit this flaw b...

CVE-2026-63919

In the Linux kernel, the following vulnerability has been resolved: xfrm: input: hold netns during deferred transport reinjection Transport-mode reinjection stores a struct net pointer in skb-cb and uses it later from xfrmtransreinject. That pointer must stay valid until the deferred callback run...

Ubuntu 20.04 LTS : Linux kernel (Azure FIPS) vulnerabilities (USN-8098-8)

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8098-8 advisory. Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module LSM. An unprivileged local attacker could use these...

kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged...
