CVE-2023-53122 Vulnerability Summary

CVE-2023-53122: In the Linux kernel, the following vulnerability has been resolved: RISC-V: fix taking the text_mutex twice during sifive errata patching Chris pointed out that some bonehead, *cough* me *cough*, added two mutex_locks() to the SiFive errata patching. The second was meant to have been a mutex_unlock(). This results in errors such as Unable to handle kernel NULL pointer dereference at virtual address 0000000000000030 Oops [#1] Modules linked in: CPU: 0 PID: 0 Comm: swapper Not tainted 6.2.0-rc1-starlight-00079-g9493e6f3ce02 #229 Hardware name: BeagleV Starlight Beta (DT) epc : __schedule+0x42/0x500 ra : schedule+0x46/0xce epc : ffffffff8065957c ra : ffffffff80659a80 sp : ffffffff81203c80 gp : ffffffff812d50a0 tp : ffffffff8120db40 t0 : ffffffff81203d68 t1 : 0000000000000001 t2 : 4c45203a76637369 s0 : ffffffff81203cf0 s1 : ffffffff8120db40 a0 : 0000000000000000 a1 : ffffffff81213958 a2 : ffffffff81213958 a3 : 0000000000000000 a4 : 0000000000000000 a5 : ffffffff80a1bd00 a6 : 0000000000000000 a7 : 0000000052464e43 s2 : ffffffff8120db41 s3 : ffffffff80a1ad00 s4 : 0000000000000000 s5 : 0000000000000002 s6 : ffffffff81213938 s7 : 0000000000000000 s8 : 0000000000000000 s9 : 0000000000000001 s10: ffffffff812d7204 s11: ffffffff80d3c920 t3 : 0000000000000001 t4 : ffffffff812e6dd7 t5 : ffffffff812e6dd8 t6 : ffffffff81203bb8 status: 0000000200000100 badaddr: 0000000000000030 cause: 000000000000000d [<ffffffff80659a80>] schedule+0x46/0xce [<ffffffff80659dce>] schedule_preempt_disabled+0x16/0x28 [<ffffffff8065ae0c>] __mutex_lock.constprop.0+0x3fe/0x652 [<ffffffff8065b138>] __mutex_lock_slowpath+0xe/0x16 [<ffffffff8065b182>] mutex_lock+0x42/0x4c [<ffffffff8000ad94>] sifive_errata_patch_func+0xf6/0x18c [<ffffffff80002b92>] _apply_alternatives+0x74/0x76 [<ffffffff80802ee8>] apply_boot_alternatives+0x3c/0xfa [<ffffffff80803cb0>] setup_arch+0x60c/0x640 [<ffffffff80800926>] start_kernel+0x8e/0x99c ---[ end trace 0000000000000000 ]--- [Palmer: pick up Geert's bug report from the thread]

Assessing the Risk of CVE-2023-53122

Access Complexity Graph

The exploitability of CVE-2023-53122 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2023-53122

No exploitability data is available for CVE-2023-53122.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2023-53122, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
