Red Hat Security Advisory: kernel-rt security and bug fix update
kernel: Intel graphics card information leak. kernel: out-of-bounds reads in pinctrl subsystem. kernel: Improper input validation in some Intel(R) Ethernet E810 Adapter drivers kernel: Insufficient access control in some Intel(R) Ethernet E810 Adapter drivers kernel: Uncontrolled resource consumption in some Intel(R) Ethernet E810 Adapter drivers kernel: Fragmentation cache not cleared on reconnection kernel: Reassembling fragments encrypted under different keys kernel: wifi frame payload being parsed incorrectly as an L2 frame kernel: Forwarding EAPOL from unauthenticated wifi client kernel: accepting plaintext data frames in protected networks kernel: not verifying TKIP MIC of fragmented frames kernel: accepting fragmented plaintext frames in protected networks kernel: accepting unencrypted A-MSDU frames that start with RFC1042 header kernel: accepting plaintext broadcast fragments as full frames kernel: reassembling encrypted fragments with non-consecutive packet numbers kernel: reassembling mixed encrypted/plaintext fragments kernel: the copy-on-write implementation can grant unintended write access because of a race condition in a THP mapcount check kernel: locking inconsistency in drivers/tty/tty_io.c and drivers/tty/tty_jobctrl.c can lead to a read-after-free kernel: buffer overflow in mwifiex_cmd_802_11_ad_hoc_start function in drivers/net/wireless/marvell/mwifiex/join.c via a long SSID value kernel: memory leak upon a kmalloc failure in kvm_io_bus_unregister_dev function in virt/kvm/kvm_main.c kernel: slab out-of-bounds read in hci_extended_inquiry_result_evt() in net/bluetooth/hci_event.c kernel: Improper access control in BlueZ may allow information disclosure vulnerability. kernel: Use-after-free in ndb_queue_rq() in drivers/block/nbd.c kernel: Linux kernel eBPF RINGBUF map oversized allocation kernel: double free in bluetooth subsystem when the HCI device initialization fails kernel: use-after-free in function hci_sock_bound_ioctl() kernel: eBPF 32-bit source register truncation on div/mod kernel: flowtable list del corruption with kernel BUG at lib/list_debug.c:50 kernel: NULL pointer dereference in llsec_key_alloc() in net/mac802154/llsec.c kernel: DoS in rb_per_cpu_empty() kernel: overlayfs: Mounting overlayfs inside an unprivileged user namespace can reveal files kernel: heap overflow in __cgroup_bpf_run_filter_getsockopt() kernel: setsockopt System Call Untrusted Pointer Dereference Information Disclosure kernel: Race condition in sctp_destroy_sock list_del kernel: fuse: stall on CPU can occur because a retry loop continually finds the same bad inode kernel: System crash in intel_pmu_drain_pebs_nhm in arch/x86/events/intel/ds.c kernel: protection for sequences of pointer arithmetic operations against speculatively out-of-bounds loads can be bypassed to leak content of kernel memory kernel: improper input validation in tipc_nl_retrieve_key function in net/tipc/node.c kernel: lack a full memory barrier upon the assignment of a new table value in net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h may lead to DoS kernel: local escalation of privileges in handling of eBPF programs kernel: protection of stack pointer against speculative pointer arithmetic can be bypassed to leak content of kernel memory kernel: out of bounds array access in drivers/md/dm-ioctl.c kernel: use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c kernel: out-of-bounds reads and writes due to enforcing incorrect limits for pointer arithmetic operations by BPF verifier kernel: NULL-deref on disconnect regression kernel: possible buffer overflow in sysfs reading
