kernel: smc: Use __sk_dst_get() and dst_dev_rcu() in smc_clc_prfx_match()

A flaw was found in the Linux kernel’s SMC Shared Memory Communication module: in smcclcprfxmatch, the function is called from smclistenwork without proper RCU or RTNL protection. The code previously used skdstgetsk-dev, which can lead to a use-after-free UAF condition if the sk’s destination is...

CVE-2026-23177

CVE-2026-23177 affects the Linux kernel's memory management (mm/shmem). A race during truncate of large swap entries could loop infinitely when an index pointed to the middle of a large swap entry and the entry didn’t cross the END boundary. The sequence could repeatedly rescan the same entry due...
