Security update for the Linux Kernel
The SUSE Linux Enterprise 15 SP2 LTSS kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2023-1637: Fixed vulnerability that could lead to unauthorized access to CPU memory after resuming CPU from suspend-to-RAM (bsc#1209779). - CVE-2022-3566: Fixed race condition in the TCP Handler (bsc#1204405). - CVE-2021-29650: Fixed an issue where the netfilter subsystem allowed attackers to cause a denial of service (bsc#1184208). - CVE-2020-36694: Fixed an use-after-free issue in netfilter in the packet processing context (bsc#1211596). - CVE-2023-1079: Fixed a use-after-free problem that could have been triggered in asus_kbd_backlight_set when plugging/disconnecting a malicious USB device (bsc#1208604). - CVE-2023-33288: Fixed a use-after-free in bq24190_remove in drivers/power/supply/bq24190_charger.c (bsc#1211590). - 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-2023-32233: Fixed a use-after-free in Netfilter nf_tables when processing batch requests (bsc#1211043). - CVE-2022-4269: Fixed a flaw was found inside the Traffic Control (TC) subsystem (bsc#1206024). - CVE-2023-1380: Fixed a slab-out-of-bound read problem in brcmf_get_assoc_ies() (bsc#1209287). - CVE-2023-2513: Fixed a use-after-free vulnerability in the ext4 filesystem (bsc#1211105). - CVE-2023-2483: Fixed a use after free bug in emac_remove caused by a race condition (bsc#1211037). - CVE-2023-23586: Fixed a memory information leak in the io_uring subsystem (bsc#1208474). - CVE-2023-2124: Fixed an out of bound access in the XFS subsystem that could have lead to denial-of-service or potentially privilege escalation (bsc#1210498). The following non-security bugs were fixed: - Drivers: hv: vmbus: Optimize vmbus_on_event (bsc#1211622). - Fix usrmerge error (boo#1211796) - ipv6: sr: fix out-of-bounds read when setting HMAC data (bsc#1211592). - kernel-binary: install expoline.o (boo#1210791 bsc#1211089) - kernel-source: Remove unused macro variant_symbols - kernel-spec-macros: Fix up obsolete_rebuilds_subpackage to generate obsoletes correctly (boo#1172073 bsc#1191731). - rpm/constraints.in: Increase disk size constraint for riscv64 to 52GB - rpm/kernel-binary.spec.in: Fix missing kernel-preempt-devel and KMP Provides (bsc#1199046) - scsi: storvsc: Parameterize number hardware queues (bsc#1211622). - usrmerge: Compatibility with earlier rpm (boo#1211796)
