CVE-2024-43843

一、漏洞信息
漏洞编号：CVE-2024-43843
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8,6.4.0,6.6.0
CVSS V2.0分值：
BaseScore：0.0 None
Vector：CVSS：2.0/
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:riscv, bpf: Fix out-of-bounds issue when preparing trampoline imageWe get the size of the trampoline image during the dry run phase andallocate memory based on that size. The allocated image will then bepopulated with instructions during the real patch phase. But aftercommit 26ef208c209a ( bpf: Use arch_bpf_trampoline_size ), the imargument is inconsistent in the dry run and real patch phase. This maycause emit_imm in RV64 to generate a different number of instructionswhen generating the im address, potentially causing out-of-boundsissues. Let s emit the maximum number of instructions for the im address during dry run to fix this problem.

CVE-2024-43843

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

riscv, bpf: Fix out-of-bounds issue when preparing trampoline image

We get the size of the trampoline image during the dry run phase and
allocate memory based on that size. The allocated image will then be
populated with instructions during the real patch phase. But after
commit 26ef208c209a ("bpf: Use arch_bpf_trampoline_size"), the im
argument is inconsistent in the dry run and real patch phase. This may
cause emit_imm in RV64 to generate a different number of instructions
when generating the 'im' address, potentially causing out-of-bounds
issues. Let's emit the maximum number of instructions for the "im"
address during dry run to fix this problem.

The Linux kernel CVE team has assigned CVE-2024-43843 to this issue.
