The Qualys Threat Research Unit (TRU) discovered that systemd-coredump is prone to a kill-and-replace race condition which may allow a local attacker to gain sensitive information from crashed SUID processes. Additionally systemd-coredump does not specify %d (the kernel's per- process "dumpable" flag) in /proc/sys/kernel/core_pattern allowing a local attacker to crash root daemons that fork() and setuid() to the attacker's uid and consequently gain read access to the resulting core dumps and therefore to sensitive information from memory of the root daemons.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

For CPUs affected to ITS (Indirect Target Selection), to fully mitigate the vulnerability it is also necessary to update the intel-microcode packages released in DSA 5924-1.

For details on the Indirect Target Selection (ITS) vulnerability please refer to https://www.vusec.net/projects/training-solo/ and https://www.intel.com/content/www/us/en/developer/articles/technical/software-security-guidance/advisory-guidance/indirect-target-selection.html .

This update ships updated CPU microcode for some types of Intel CPUs. In particular it provides mitigations for the Indirect Target Selection (ITS) vulnerability (CVE-2024-28956) and the Branch Privilege Injection vulnerability (CVE-2024-45332).

For CPUs affected to ITS (Indirect Target Selection), to fully mitigate the vulnerability it is also necessary to update the Linux kernel packages released in a separate, forthcoming DSA.

For details on the Indirect Target Selection (ITS) vulnerability please refer to https://www.vusec.net/projects/training-solo/ and https://www.intel.com/content/www/us/en/developer/articles/technical/software-security-guidance/advisory-guidance/indirect-target-selection.html .
