Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Use-after-free
EUVDB-ID: #VU72098
Risk: Low
CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-0590
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the qdisc_graft() function in net/sched/sch_api.c. A local user can trigger a use-after-free error and crash the kernel.
Update the affected package the Linux Kernel RT (Live Patch 1 for SLE 15 SP4) to the latest version.

2) Use-after-free
EUVDB-ID: #VU72734
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-2023-1118
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in the Linux kernel integrated infrared receiver/transceiver driver "drivers/media/rc/ene_ir.c" when detaching rc device. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel RT (Live Patch 1 for SLE 15 SP4) to the latest version.
