The allocated image will then be\npopulated with instructions during the real patch phase. But after\ncommit 26ef208c209a (\"bpf: Use arch_bpf_trampoline_size\"), the `im`\nargument is inconsistent in the dry run and real patch phase. This may\ncause emit_imm in RV64 to generate a different number of instructions\nwhen generating the 'im' address, potentially causing out-of-bounds\nissues. Let's emit the maximum number of instructions for the \"im\"\naddress during dry run to fix this problem.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-131"],"references":["https://git.kernel.org/stable/c/3e6a1b1b179abb643ec3560c02bc3082bc92285f","https://git.kernel.org/stable/c/9f1e16fb1fc9826001c69e0551d51fbbcd2d74e9"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:54:16.205165117+00:00"},"epss":{"cve":"CVE-2024-43843","score":0.00204,"percentile":0.10411,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
