Summary

Moderate: kernel-rt security and bug fix update

Details

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

• off-path attacker may inject data or terminate victim's TCP session (CVE-2020-36516)
• use-after-free vulnerability in function scosocksendmsg() (CVE-2021-3640)
• smb2ioctlquery_info NULL pointer dereference (CVE-2022-0168)
• NULL pointer dereference in udfexpandfile_adinicbdue() during writeback (CVE-2022-0617)
• swiotlb information leak with DMAFROMDEVICE (CVE-2022-0854)
• uninitialized registers on stack in nftdochain can cause kernel pointer leakage to UM (CVE-2022-1016)
• race condition in sndpcmhw_free leading to use-after-free (CVE-2022-1048)
• use-after-free and memory errors in ext4 when mounting and operating on a corrupted image (CVE-2022-1184)
• concurrency use-after-free between drmsetmasterioctl and drmmodegetresources (CVE-2022-1280)
• kernel info leak issue in pfkey_register (CVE-2022-1353)
• use-after-free in ath9khtcprobe_device() could cause an escalation of privileges (CVE-2022-1679)
• NULL pointer dereference in x86emulateinsn may lead to DoS (CVE-2022-1852)
• fanotify misuses fd_install() which could lead to use-after-free (CVE-2022-1998)
• nf_tables cross-table potential use-after-free may lead to local privilege escalation (CVE-2022-2586)
• openvswitch: integer underflow leads to out-of-bounds write in reservesfasize() (CVE-2022-2639)
• slab-out-of-bounds access in packet_recvmsg() (CVE-2022-20368)
• incomplete clean-up of multi-core shared buffers (aka SBDR) (CVE-2022-21123)
• incomplete clean-up of microarchitectural fill buffers (aka SBDS) (CVE-2022-21125)
• incomplete clean-up in specific special register write operations (aka DRPW) (CVE-2022-21166)
• possible to use the debugger to write zero into a location of choice (CVE-2022-21499)
• AMD: RetBleed Arbitrary Speculative Code Execution with Return Instructions (CVE-2022-23816, CVE-2022-29900)
• AMD: Branch Type Confusion (non-retbleed) (CVE-2022-23825)

• use after free in SUNRPC subsystem (CVE-2022-28893)
• use-after-free due to improper update of reference count in net/sched/cls_u32.c (CVE-2022-29581)
• Intel: RetBleed Arbitrary Speculative Code Execution with Return Instructions (CVE-2022-29901)
• DoS in nfqnlmangle in net/netfilter/nfnetlinkqueue.c (CVE-2022-36946)
• nf_tables disallow binding to already bound chain (CVE-2022-39190)
• nfsatomicopen() returns uninitialized data instead of ENOTDIR (CVE-2022-24448)
