{"schemaVersion":3,"id":"SUSE-SU-2023:3324-1","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Security update for the Linux Kernel\n\n\nThe SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes.\n\n\nThe following security bugs were fixed:\n\n- CVE-2018-20784: Fixed a denial of service (infinite loop in update_blocked_averages) by mishandled leaf cfs_rq in kernel/sched/fair.c (bsc#1126703).\n- CVE-2018-3639: Fixed Speculative Store Bypass aka 'Memory Disambiguation' (bsc#1087082).\n- CVE-2022-40982: Fixed transient execution attack called 'Gather Data Sampling' (bsc#1206418).\n- CVE-2023-0459: Fixed information leak in __uaccess_begin_nospec (bsc#1211738).\n- CVE-2023-1637: Fixed vulnerability that could lead to unauthorized access to CPU memory after resuming CPU from suspend-to-RAM (bsc#1209779).\n- CVE-2023-20569: Fixed side channel attack ‘Inception’ or ‘RAS Poisoning’ (bsc#1213287).\n- CVE-2023-20593: Fixed a ZenBleed issue in 'Zen 2' CPUs that could allow an attacker to potentially access sensitive information (bsc#1213286).\n- CVE-2023-2985: Fixed an use-after-free vulnerability in hfsplus_put_super in fs/hfsplus/super.c that could allow a local user to cause a denial of service (bsc#1211867).\n- CVE-2023-3106: Fixed crash in XFRM_MSG_GETSA netlink handler (bsc#1213251).\n- CVE-2023-3268: Fixed an out of bounds memory access flaw in relay_file_read_start_pos in the relayfs (bsc#1212502).\n- CVE-2023-35001: Fixed an out-of-bounds memory access flaw in nft_byteorder that could allow a local attacker to escalate their privilege (bsc#1213059).\n- CVE-2023-3567: Fixed a use-after-free in vcs_read in drivers/tty/vt/vc_screen.c (bsc#1213167).\n- CVE-2023-3611: Fixed an out-of-bounds write in net/sched sch_qfq(bsc#1213585).\n- CVE-2023-3776: Fixed improper refcount update in  cls_fw leads to use-after-free (bsc#1213588).\n\nThe following non-security bugs were fixed:\n\n- net/sched: sch_qfq: refactor parsing of netlink parameters (bsc#1213585).\n- ubi: Fix failure attaching when vid_hdr offset equals to (sub)page size (bsc#1210584).\n- ubi: ensure that VID header offset + VID header size &lt;= alloc, size (bsc#1210584).\n- x86: Treat R_X86_64_PLT32 as R_X86_64_PC32 (git-fixes) No it's not git-fixes it's used to make sle12-sp2 compile with newer toolchain to make the life of all the poor souls maintaining this ancient kernel on their modern machines, a little bit easier....","dates":{"published":"2023-08-16T06:13:06.000Z","modified":"2026-02-04T02:31:16.170Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"suse","product":"kernel-default&distro=SUSE
