ALSA-2022:7318 — Important: kernel security, bug fix, and enhancement update

Affected: AlmaLinux:9: bpftool, AlmaLinux:9: kernel, AlmaLinux:9: kernel-abi-stablelists, AlmaLinux:9: kernel-core, AlmaLinux:9: kernel-cross-headers, AlmaLinux:9: kernel-debug, AlmaLinux:9: kernel-debug-core, AlmaLinux:9: kernel-debug-devel, AlmaLinux:9: kernel-debug-devel-matched, AlmaLinux:9: kernel-debug-modules and 18 more

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

Security Fix(es):

* posix cpu timer use-after-free may lead to local privilege escalation (CVE-2022-2585) * Unprivileged users may use PTRACE_SEIZE to set PTRACE_O_SUSPEND_SECCOMP option (CVE-2022-30594)

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):

* kernel crash after reboot of T14/G2 AMD laptop (mt7921e module) (BZ#2095653) * execve exit tracepoint not called (BZ#2106661) * Matrox black screen on VGA output on some systems. (BZ#2112017) * The kernel needs to offer a way to reseed the Crypto DRBG and atomically extract random numbers from it (BZ#2121129) * watchdog BUG: soft lockup - CPU#30 stuck for 34s! [swapper/30:0] (BZ#2127857) * Update cifs to 5.16 (BZ#2127858) * Bad page state in process qemu-kvm pfn:68a74600 (BZ#2127859) * vfio zero page mappings fail after 2M instances (BZ#2128791) * The kernel needs to offer a way to reseed the Crypto DRBG and atomically extract random numbers from it (part 2) (BZ#2128970)

Enhancement(s):

* Need to enable hpilo to support new HPE RL300 Gen11 for ARM (aarch64) (BZ#2129453)

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.

ICSA-23-166-10 — Siemens SIMATIC S7-1500 TM MFP BIOS

The iconv program in the GNU C Library (aka glibc or libc6) 2.31 and earlier, when invoked with multiple suffixes in the destination encoding (TRANSLATE or IGNORE) along with the -c option, enters an infinite loop when processing invalid multi-byte input sequences, leading to a denial of service. The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-byte input sequences in the EUC-KR encoding, may have a buffer over-read. A use-after-free vulnerability introduced in glibc upstream version 2.14 was found in the way the tilde expansion was carried out. Directory paths containing an initial tilde followed by a valid username were affected by this issue. A local attacker could exploit this flaw by creating a specially crafted path that, when processed by the glob function, would potentially lead to arbitrary code execution. This was fixed in version 2.32. The GNU C Library (aka glibc or libc6) before 2.32 could overflow an on-stack buffer during range reduction if an input to an 80-bit long double function contains a non-canonical bit pattern, a seen when passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to sysdeps/ieee754/ldbl-96/e_rem_pio2l.c. The iconv function in the GNU C Library (aka glibc or libc6) 2.32 and earlier, when processing invalid multi-byte input sequences in IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 encodings, fails to advance the input state, which could lead to an infinite lo…

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)
