| Subject: CVE-2024-38579: crypto: bcm - Fix pointer arithmetic |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| crypto: bcm - Fix pointer arithmetic |
| |
| In spu2_dump_omd() value of ptr is increased by ciph_key_len |
| instead of hash_iv_len which could lead to going beyond the |
| buffer boundaries. |
| Fix this bug by changing ciph_key_len to hash_iv_len. |
| |
| Found by Linux Verification Center (linuxtesting.org) with SVACE. |
| |
| The Linux kernel CVE team has assigned CVE-2024-38579 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
