title: Red Hat Security Advisory: kernel-alt security, bug fix, and enhancement update
description: hw: cpu: speculative execution bounds-check bypass kernel: Buffer overflow in mp_override_legacy_irq() kernel: memory leak when merging buffers in SCSI IO vectors kernel: NULL pointer dereference due to KEYCTL_READ on negative key kernel: net: double-free and memory corruption in get_net_ns_by_id() kernel: Incorrect updates of uninstantiated keys crash the kernel Kernel: KVM: oops when checking KVM_CAP_PPC_HTM on PPC platform Kernel: ipsec: xfrm: use-after-free leading to potential privilege escalation kernel: Missing capabilities check in net/netfilter/nfnetlink_cthelper.c allows for unprivileged access to systemwide nfnl_cthelper_list structure kernel: Missing namespace check in net/netlink/af_netlink.c allows for network monitors to observe systemwide activity kernel: Arbitrary stack overwrite causing oops via crafted signal frame kernel: Stack information leak in the EFS element kernel: Integer overflow in futex.c:futux_requeue can lead to denial of service or unspecified impact kernel: Race condition in sound system can lead to denial of service
