Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2024:1722533082 advisory.

- In the Linux kernel, the following vulnerability has been resolved: i2c: Fix a potential use after free Free the adap structure only after we are done using it. This patch just moves the put_device() down a bit to avoid the use after free. [wsa: added comment to the code, added Fixes tag] (CVE-2019-25162)

- In the Linux kernel, the following vulnerability has been resolved: tty: tty_buffer: Fix the softlockup issue in flush_to_ldisc When running ltp testcase(ltp/testcases/kernel/pty/pty04.c) with arm64, there is a soft lockup, which look like this one: Workqueue: events_unbound flush_to_ldisc Call trace:

At the same time, the workqueue will do the flush_to_ldisc to pop data in a loop until there is no more data left. When the sender and workqueue running in different core, the sender sends data fastly in full time which will result in workqueue doing work in loop for a long time and occuring softlockup in flush_to_ldisc with kernel configured without preempt. So I add need_resched check and cond_resched in the flush_to_ldisc loop to avoid it. (CVE-2021-47185)

- A flaw was found in the filelock_init in fs/locks.c function in the Linux kernel. This issue can lead to host memory exhaustion due to memcg not limiting the number of Portable Operating System Interface (POSIX) file locks. (CVE-2022-0480)

- A flaw was found in the Linux kernel 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. (CVE-2022-2977)

- A vulnerability has been found in Linux Kernel up to 5.10.162/5.15.85/6.0.15/6.1.1. The impacted element is the function btf_dump_name_dups of the file tools/lib/bpf/btf_dump.c of the component libbpf. The manipulation leads to use after free. Upgrading to version 5.10.163, 5.15.86, 6.0.16, 6.1.2 and 6.2 is sufficient to resolve this issue. The identifier of the patch is c61650b869e0b6fb0c0a28ed42d928eea969afc8/ fbe08093fb2334549859829ef81d42570812597d/8c64a8e76eb85d422af5ec60ccbf26e3ead8c333/a733bf10198eb5bb92789094 0de8ab457491ed3b/93c660ca40b5d2f7c1b1626e955a8e9fa30e0749. You should upgrade the affected component.
(CVE-2022-3534)
