CVE-2025-71298

In CVE-2025-71298, the Linux kernel fix targets drm_gem_shmem_madvise_locking: the GEM object reservation lock is now held around the madvise path to correct locking in shmem tests. The update exposes a dedicated helper drm_gem_shmem_madvise() for Kunit tests (not intended as a driver interface)....

CVE-2025-71298 drm/tests: shmem: Hold reservation lock around madvise

In the Linux kernel, the following vulnerability has been resolved: drm/tests: shmem: Hold reservation lock around madvise Acquire and release the GEM object's reservation lock around calls to the object's madvide operation. The tests use drmgemshmemmadviselocked, which led to errors such as show...

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...
