SUSE CVE-2026-31664

In the Linux kernel, the following vulnerability has been resolved: xfrm: clear trailing padding in buildpolexpire buildexpire clears the trailing padding bytes of struct xfrmuserexpire after setting the hard field via memsetafter, but the analogous function buildpolexpire does not do this for...

CVE-2026-31671

A flaw was found in the Linux kernel's xfrmuser component. This vulnerability allows a local attacker to disclose sensitive information. The xfrmuserreport structure contains uninitialized padding bytes that are copied to userspace, leading to an information leak...

CVE-2026-31664

A flaw was found in the Linux kernel's xfrm subsystem. This vulnerability arises because the buildpolexpire function does not clear trailing padding bytes within the xfrmuserpolexpire structure. Consequently, these uninitialized padding bytes, which contain kernel heap memory contents, are sent t...

CVE-2026-31663

A flaw was found in the Linux kernel's xfrm IP eXtensible FRamework subsystem. This vulnerability involves a race condition where a network device's reference is released too early during packet processing after asynchronous cryptography. This premature release can lead to the system attempting t...
