Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Permissions, Privileges, and Access Controls
EUVDB-ID: #VU75163
Risk: Low
CVSSv4.0: 1.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2023-2002
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper permissions check in the Bluetooth subsystem when handling ioctl system calls of HCI sockets. A local user can acquire a trusted socket, leading to unauthorized execution of management commands.
Update the affected package the Linux Kernel (Live Patch 29 for SLE 15 SP2) to the latest version.

2) Use-after-free
EUVDB-ID: #VU78064
Risk: Low
CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-3159
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 within the outbound_phy_packet_callback() function in driver/firewire in Linux kernel. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
Update the affected package the Linux Kernel (Live Patch 29 for SLE 15 SP2) to the latest version.

3) Out-of-bounds write
EUVDB-ID: #VU77502
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-2023-35788
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
Description The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the fl_set_geneve_opt() function in net/sched/cls_flower.c in Linux kernel. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
