CVE-2024-46797

In the Linux kernel, the following vulnerability has been resolved: powerpc/qspinlock: Fix deadlock in MCS queue If an interrupt occurs in queuedspinlockslowpath after we increment qnodesp-count and before node-lock is initialized, another CPU might see stale lock values in gettailqnode. If the...

CVE-2024-46791

CVE-2024-46791 concerns the Linux kernel, where a deadlock can occur in the MCP251X CAN driver if an interrupt arrives while mcp251x_open holds priv->mcp_lock. The root cause is that mcp251x_hw_wake() disables interrupts with the mutex still held, causing the interrupt handler to deadlock when...
