ALSA-2022:7110 — Important: kernel security, bug fix, and enhancement update

Affected: AlmaLinux:8: bpftool, AlmaLinux:8: kernel, AlmaLinux:8: kernel-abi-stablelists, AlmaLinux:8: kernel-core, AlmaLinux:8: kernel-cross-headers, AlmaLinux:8: kernel-debug, AlmaLinux:8: kernel-debug-core, AlmaLinux:8: kernel-debug-devel, AlmaLinux:8: kernel-debug-modules, AlmaLinux:8: kernel-debug-modules-extra and 10 more

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* A use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588) * Information leak in scsi_ioctl() (CVE-2022-0494) * A kernel-info-leak issue in pfkey_register (CVE-2022-1353) * RetBleed Arbitrary Speculative Code Execution with Return Instructions (CVE-2022-23816, CVE-2022-29900) * Branch Type Confusion (non-retbleed) (CVE-2022-23825) * RetBleed Arbitrary Speculative Code Execution with Return Instructions (CVE-2022-29901)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

* Add s390_iommu_aperture kernel parameter (BZ#2081324) * Blackscreen and hangup after resume from hibernate or S3 with DFGX WX3200 (BZ#2091065) * Update NVME subsystem with bug fixes and minor changes (BZ#2106017) * Fix parsing of nw_proto for IPv6 fragments (BZ#2106703) * "vmcore failed, _exitcode:139" error observed while capturing vmcore during fadump after memory remove. incomplete vmcore is captured. (BZ#2107488) * 'disable_policy' is ignored for addresses configured on a down interface (BZ#2109971) * Backport request for new cpufreq.default_governor kernel command line parameter (BZ#2109996) * Panics in mpt3sas mpt3sas_halt_firmware() if mpt3sas_fwfault_debug=1 enabled when poweroff issued to server (BZ#2…

It was discovered that the cls_route filter implementation in the Linux kernel would not remove an old filter from the hashtable before freeing it if its handle had the value 0.

ICSA-23-075-01 — Siemens SCALANCE, RUGGEDCOM Third-Party

zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches. An information disclosure vulnerability exists when certain central processing units (CPU) speculatively access memory, aka 'Windows Kernel Information Disclosure Vulnerability'. This CVE ID is unique from CVE-2019-1071, CVE-2019-1073. A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine. A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of service (DOS) due to a deadlock problem. LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs. A NULL pointer dereference in Busybox's man applet leads to denial of service when a section name is supplied but no page argument is given. An out-of-bounds hea…

OESA-2022-1845 — kernel security update

Affected: openEuler:22.03-LTS: kernel

Security Fix(es): st21nfca_connectivity_event_received in drivers/nfc/st21nfca/se.c in the Linux kernel through 5.16.12 has EVT_TRANSACTION buffer overflows because of untrusted length parameters.(CVE-2022-26490) The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This allows Xen PV guest OS users to cause a denial of service or gain privileges.(CVE-2022-36123)

A use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the Linux kernel. This flaw allows a local, privileged attacker to crash the system, possibly leading to a local privilege escalation issue.(CVE-2022-2588)

It was discovered that when exec ing from a non-leader thread, armed POSIX CPU timers would be left on a list but freed, leading to a use-after-free.(CVE-2022-2585)
