1) Improper locking
EUVDB-ID: #VU92035
Risk: Low
CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2024-26923
CWE-ID:
CWE-667 - Improper Locking
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper locking within the unix_gc() function in net/unix/garbage.c due to garbage collector does not take into account the risk of embryo getting enqueued during the garbage collection. A local user can execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel (Live Patch 0 for SLE 15 SP6) to the latest version.

2) Use-after-free
EUVDB-ID: #VU89672
Risk: Medium
CVSSv4.0: 5.7 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green]
CVE-ID: CVE-2024-27398
CWE-ID:
CWE-416 - Use After Free
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the sco_sock_timeout() function in net/bluetooth/sco.c. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.
Update the affected package the Linux Kernel (Live Patch 0 for SLE 15 SP6) to the latest version.
