CVE-2023-54087

In the Linux kernel ubi subsystem, CVE-2023-54087 fixes a null pointer dereference in ubi_free_volume() triggered when ubi_add_volume() failures lead to kill_volumes() invoking ubi_free_volume() for devices that may not have been added. The patch ensures that, on ubi_add_volume() error, the affec...

CVE-2023-54086 bpf: Add preempt_count_{sub,add} into btf id deny list

CVE-2023-54086

The CVE targets the Linux kernel’s BPF trampoline handling. It describes a vulnerability where preempt_count_sub/add was left unprotected in __bpf_prog_enter_recur/__bpf_prog_exit_recur, causing panics and stack/IRQ guard page errors when trampolines are attached. The fix is to add these two func...
