CVE-2023-53987

A flaw was found in the Linux kernel. A local attacker could exploit a potential NULL dereference vulnerability in the ping socket handling when accessing /proc/net/icmp. This issue arises from an incorrect use of Read-Copy Update RCU instead of a spinlock. Successful exploitation of this flaw...

CVE-2023-54028

The CVE concerns the Linux kernel RDMA/rxe path. If rxe_create_qp() triggers an error before rxe_init_task() is executed, an unwind may run rxe_cleanup() and reach rxe_cleanup_task(), which can oops when accessing an uninitialized spinlock. The root cause is registration of a non-static key in rx...
