| Subject: CVE-2024-26655: Fix memory leak in posix_clock_open() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| Fix memory leak in posix_clock_open() |
| |
| If the clk ops.open() function returns an error, we don't release the |
| pccontext we allocated for this clock. |
| |
| Re-organize the code slightly to make it all more obvious. |
| |
| The Linux kernel CVE team has assigned CVE-2024-26655 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: |
| https://git.kernel.org/stable/c/a88649b49523e8cbe95254440d803e38c19d2341 |
