| Subject: CVE-2024-47735: RDMA/hns: Fix spin_unlock_irqrestore() called with IRQs enabled |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| RDMA/hns: Fix spin_unlock_irqrestore() called with IRQs enabled |
| |
| Fix missuse of spin_lock_irq()/spin_unlock_irq() when |
| spin_lock_irqsave()/spin_lock_irqrestore() was hold. |
| |
| This was discovered through the lock debugging, and the corresponding |
| log is as follows: |
| |
| raw_local_irq_restore() called with IRQs enabled |
| WARNING: CPU: 96 PID: 2074 at kernel/locking/irqflag-debug.c:10 warn_bogus_irq_restore+0x30/0x40 |

| 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: |
