CVE-2024-38557 net/mlx5: Reload only IB representors upon lag disable/enable

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Reload only IB representors upon lag disable/enable On lag disable, the bond IB device along with all of its representors are destroyed, and then the slaves' representors get reloaded. In case the slave IB representor...

CVE-2024-38556

CVE-2024-38556 affects the Linux kernel net/mlx5 code. The vulnerability arises from how the command queue semaphore timeout handling can allow an entry to be processed before an index is allocated, risking an out-of-bounds access at idx = -22 if the completion path proceeds without proper synchr...

CVE-2024-38555 net/mlx5: Discard command completions in internal error

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Discard command completions in internal error Fix use after free when FW completion arrives while device is in internal error state. Avoid calling completion handler in this case, since the device will flush the command...

CVE-2024-38555

CVE-2024-38555: In the Linux kernel, the net/mlx5 driver fixes a use-after-free by discarding FW command completions arriving during an internal error state. The patch prevents calling the completion handler when the device will flush the command interface, avoiding use-after-free/refcount underf...

CVE-2024-38556 net/mlx5: Add a timeout to acquire the command queue semaphore

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Add a timeout to acquire the command queue semaphore Prevent forced completion handling on an entry that has not yet been assigned an index, causing an out of bounds access on idx = -22. Instead of waiting indefinitely...
