Linux Kernel Security Vulnerabilities

The Linux kernel version 6.10 contains security vulnerabilities. These vulnerabilities arise from the mm/slab mechanism, which causes unbounded recursion when allocating the objexts array between kmalloc buffers during the release process. This can lead to a stack overflow...

SUSE CVE-2025-40348

In the Linux kernel, the following vulnerability has been resolved: slab: Avoid race on slab-objexts in allocslabobjexts If two competing threads enter allocslabobjexts and one of them fails to allocate the object extension vector, it might override the valid slab-objexts allocated by the other...

CVE-2025-68199

In the Linux kernel, the following vulnerability has been resolved: codetag: debug: handle existing CODETAGEMPTY in markobjextsempty for slabobjext When allocslabobjexts fails and then later succeeds in allocating a slab extension vector, it calls handlefailedobjextsalloc to mark all objects in t...

DEBIAN-CVE-2025-37908

In the Linux kernel, the following vulnerability has been resolved: mm, slab: clean up slab-objexts always When memory allocation profiling is disabled at runtime or due to an error, shutdownmemprofiling is called: slab-objexts which previously allocated remains. It won't be cleared by...

CVE-2024-46789

CVE-2024-46789 (Linux kernel) details from connected documents show a concrete fix: in mm/slub, the tagging logic now checks s->flags in alloc_tagging_slab_free_hook to avoid calling alloc_tag_add when SLAB_NO_OBJ_EXT or SLAB_NOLEAKTRACE are set. This prevents the NULL ref (ref->ct) and the...
