CVE-2022-1462

The Linux Kernel, the operating system core itself.

Security Fix(es):

A race condition in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc.(CVE-2022-1729)

A use-after-free flaw was found in nf_tables cross-table in the net/netfilter/nf_tables_api.c function in the Linux kernel. This flaw allows a local, privileged attacker to cause a use-after-free problem at the time of table deletion, possibly leading to local privilege escalation.(CVE-2022-2586)

Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates. We recommend upgrading past commit 4caae58406f8ceb741603eee460d79bacca9b1b5(CVE-2022-2503)

An out-of-bounds read flaw was found in the Linux kernel’s TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory.(CVE-2022-1462)

A race condition was found in the Linux kernel's watch queue due to a missing lock in pipe_resize_ring(). The specific flaw exists within the handling of pipe buffers. The issue results from the lack of proper locking when performing operations on an object. This flaw allows a local user to crash the system or escalate their privileges on the system.(CVE-2022-2959)

A flaw was found in the kernels implementation of proxied virtualized TPM devices. On a system where virtualized TPM devices are configured (this is not the default) a local attacker can create a use-after-free and create a situation where it may be possible to escalate privileges on the system.

The linux kernels driver for the "ASIX AX88179_178A based USB 2.0/3.0 Gigabit Ethernet Devices" contains multiple out-of-bounds reads and possible writes in the ax88179_rx_fixup() function.

A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket.(CVE-2022-3028)

An out-of-bounds read flaw was found in the Linux kernel’s TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory.

These are all security issues fixed in the kernel-devel-longterm-6.6.17-1.1 package on the GA media of openSUSE Tumbleweed.

The SUSE Linux Enterprise 15 SP4 kernel was updated.

The following security bugs were fixed:

• CVE-2022-29900, CVE-2022-29901: Fixed the RETBLEED attack, a new Spectre like Branch Target Buffer attack, that can leak arbitrary kernel information (bsc#1199657).

• CVE-2022-29582: Fixed a use-after-free due to a race condition in io_uring timeouts. This can be triggered by a local user who has no access to any user namespace; however, the race condition perhaps can only be exploited infrequently. (bnc#1198811)
• CVE-2022-0494: Fixed a kernel information leak flaw in the scsi_ioctl function. This flaw allowed a local attacker with a special user privilege to create issues with confidentiality. (bnc#1197386)
• CVE-2021-4204: Fixed a vulnerability that allows local attackers to escalate privileges on affected installations via ebpf. (bnc#1194111)
• CVE-2022-23222: Fixed a bug that allowed local users to gain privileges. (bnc#1194765)
• CVE-2022-0264: Fixed a vulnerability in the Linux kernel's eBPF verifier when handling internal data structures. Internal memory locations could be returned to userspace. A local attacker with the permissions to insert eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit mitigations in place for the kernel. (bnc#1194826)
• CVE-2022-1016: Fixed a vulnerability in the nf_tables component of the netfilter subsystem. This vulnerability gives an attacker a powerful primitive that can be used to both read from and…
