The SUSE Linux Enterprise 12 SP4 LTSS kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2022-3566: Fixed race condition in the TCP Handler (bsc#1204405). - CVE-2022-45886: Fixed a .disconnect versus dvb_device_open race condition in dvb_net.c that lead to a use-after-free (bsc#1205760). - CVE-2022-45885: Fixed a race condition in dvb_frontend.c that could cause a use-after-free when a device is disconnected (bsc#1205758). - CVE-2022-45887: Fixed a memory leak in ttusb_dec.c caused by the lack of a dvb_frontend_detach call (bsc#1205762). - CVE-2022-45919: Fixed a use-after-free in dvb_ca_en50221.c that could occur if there is a disconnect after an open, because of the lack of a wait_event (bsc#1205803). - CVE-2022-45884: Fixed a use-after-free in dvbdev.c, related to dvb_register_device dynamically allocating fops (bsc#1205756). - CVE-2023-31084: Fixed a blocking issue in drivers/media/dvb-core/dvb_frontend.c (bsc#1210783). - CVE-2023-31436: Fixed an out-of-bounds write in qfq_change_class() because lmax can exceed QFQ_MIN_LMAX (bsc#1210940 bsc#1211260). - CVE-2023-2194: Fixed an out-of-bounds write vulnerability in the SLIMpro I2C device driver (bsc#1210715). - CVE-2023-32269: Fixed a use-after-free in af_netrom.c, related to the fact that accept() was also allowed for a successfully connected AF_NETROM socket (bsc#1211186). - CVE-2023-1380: A slab-out-of-bound read problem was fixed in brcmf_get_assoc_ies(), that could lead to a denial of service (bsc#1209287). - CVE-2023-2513: A use-after-free vulnerability was fixed in the ext4 filesystem, related to the way it handled the extra inode size for extended attributes (bsc#1211105). - CVE-2023-2176: A vulnerability was found in compare_netdev_and_ip in drivers/infiniband/core/cma.c in RDMA. The improper cleanup results in out-of-boundary read, where a local user can utilize this problem to crash the system or escalation of privilege (bsc#1210629). The following non-security bugs were fixed: - ext4: add EXT4_INODE_HAS_XATTR_SPACE macro in xattr.h (bsc#1206878). - ipv6: sr: fix out-of-bounds read when setting HMAC data (bsc#1211592).
