CVE-2022-49700

CVE-2022-49700 is a Linux kernel SLUB allocator bug: the fastpath in slab_alloc_node() can race with slab deactivation, allowing a mismatch where c->slab/c->freelist become inconsistent and can lead to a use-after-free or a page freeing while it still contains slab objects. The issue is tie...

CVE-2022-49697

CVE-2022-49697 concerns a leak in the Linux kernel caused by a BPF lookup path that could leak a request_sock. The issue occurs when a BPF program performs a socket lookup that takes a refcnt on the socket and, after locating the child request_socket, returns the parent LISTEN socket via sk_to_fu...
