Slackware Linux 15.0 kernel-generic Multiple Vulnerabilities (SSA:2023-359-01)

medium Nessus Plugin ID 187293

Language:

Synopsis

The remote Slackware Linux host is missing a security update to kernel-generic.

Description

The version of kernel-generic installed on the remote host is prior to 5.15.145 / 5.15.145_smp. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-359-01 advisory.

 - An issue was discovered in the Linux kernel through 6.5.9. During a race with SQ thread exit, an io_uring/fdinfo.c io_uring_show_fdinfo NULL pointer dereference can occur. (CVE-2023-46862)

 - An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).
 (CVE-2023-6121)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the affected kernel-generic package.
