# CVE-2024-50203: linux: In the Linux kernel, the following vulnerability has been resolved: bpf, arm64: Fix address emission with tag-based... CVE-2024-50203 is fixed in 26 products on 1 platform, first by DEBIAN-CVE-2024-50203, released November 8, 2024. It is not reported as exploited. Patch Radar priority: High. - Web page: https://patchblox.com/security/cve/CVE-2024-50203 - Priority: High - CVSS: 7.8 (high) - EPSS: 0.0023 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Nov 8, 2024 ## Description In the Linux kernel, the following vulnerability has been resolved: bpf, arm64: Fix address emission with tag-based KASAN enabled When BPF_TRAMP_F_CALL_ORIG is enabled, the address of a bpf_tramp_image struct on the stack is passed during the size calculation pass and an address on the heap is passed during code generation. This may cause a heap buffer overflow if the heap address is tagged because emit_a64_mov_i64() will emit longer code than it did during the size calculation pass. The same problem could occur without tag-based KASAN if one of the 16-bit words of the stack address happened to be all-ones during the size calculation pass. Fix the problem by assuming the worst case (4 instructions) when calculating the size of the bpf_tramp_image address emission. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released |
