The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * kernel: use-after-free in __blk_add_trace in kernel/trace/blktrace.c * kernel: nfs: NULL pointer dereference due to an anomalized NFS message sequence * kernel: memory leak in the kernel_read_file function in fs/exec.c allows to cause a denial of service * kernel: unprivileged users able to create RAW sockets in AF_IEEE802154 network protocol. * kernel: unprivileged users able to create RAW sockets in AF_ISDN network protocol. * kernel: integer overflow in tcp_ack_update_rtt in net/ipv4/tcp_input.c * kernel: information leak bug caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_core.c driver * kernel: some ipv6 protocols not encrypted over ipsec tunnel. * Kernel: net: using kernel space address bits to derive IP ID may potentially break KASLR * kernel: An out-of-bounds read in drivers/scsi/qedi/qedi_dbg.c leading to crash or information disclosure * kernel: a NULL pointer dereference in drivers/net/wireless/ath/ath10k/usb.c leads to a crash * kernel: Null pointer dereference in the sound/usb/line6/pcm.c * kernel: Two memory leaks in the mwifiex_pcie_init_evt_ring function in drivers/net/wireless/marvell/mwifiex/pcie.c allows for a DoS * kernel: Memory leaks in drivers/net/wireless/ath/ath9k/htc_hst.c in the Linux kernel * kernel: a memory leak in the ath9k management function in allows local DoS * kernel: when cpu.cfs_quota_us is used allows attackers to cause a denial of service against non-cpu-bound applications For more details about the security issue, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.
