The SUSE Linux Enterprise 15 SP4 RT kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2023-2235: A use-after-free vulnerability in the Performance Events system can be exploited to achieve local privilege escalation (bsc#1210986). - CVE-2022-2196: Fixed a regression related to KVM that allowed for speculative execution attacks (bsc#1206992). - CVE-2023-23006: Fixed NULL checking against IS_ERR in dr_domain_init_resources (bsc#1208845). - CVE-2023-1670: Fixed a use after free in the Xircom 16-bit PCMCIA Ethernet driver. A local user could use this flaw to crash the system or potentially escalate their privileges on the system (bsc#1209871). - 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). - CVE-2023-0386: A flaw was found where unauthorized access to the execution of the setuid file with capabilities was found in the OverlayFS subsystem, when a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allowed a local user to escalate their privileges on the system (bsc#1209615). - CVE-2023-1998: Fixed a use after free during login when accessing the shost ipaddress (bsc#1210506). - CVE-2023-1855: Fixed a use after free in xgene_hwmon_remove (bsc#1210202). - CVE-2023-30772: Fixed a race condition and resultant use-after-free in da9150_charger_remove (bsc#1210329). - CVE-2023-2019: A flaw was found in the netdevsim device driver, more specifically within the scheduling of events. This issue results from the improper management of a reference count and may lead to a denial of service (bsc#1210454). - CVE-2023-2008: A flaw was found in the fault handler of the udmabuf device driver. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code (bsc#1210453). - CVE-2023-1989: Fixed a use after free in btsdio_remove (bsc#1210336). - CVE-2023-1990: Fixed a use after free in ndlc_remove (bsc#1210337).
