CVE-2023-52626

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix operation precedence bug in port timestamping napipoll context Indirection is of lower precedence than postfix increment ++. Logic in napipoll context would cause an out-of-bound read by first increment the pointer...

CVE-2023-52626

CVE-2023-52626 (Linux kernel) affects net/mlx5e: fix an operation precedence bug in port timestamping napi_poll context, where indirection (*) has lower precedence than postfix ++, causing an out-of-bounds read after increment. The fix dereferences before increment, preventing the read. CVSS 3.1 ...

CVE-2021-47164

A vulnerability was found in the net/mlx5e driver in the Linux kernel where a NULL pointer dereference was caused when accessing a lag device. This issue occurred because the driver processed an event without confirming the existence of an upper device, which led to potential crashes. Mitigation...

CVE-2021-47164

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix null deref accessing lag dev It could be the lag dev is null so stop processing the event. In bondenslave the active/backup slave being set before setting the upper dev so first event is without an upper dev. After...

CVE-2021-47164

CVE-2021-47164 is a Linux kernel vulnerability fixed by correcting a NULL dereference in net/mlx5e related to lag device handling. Explanation: in bond_enslave(), the active/backup slave was set before the upper dev is assigned; a second event with an upper dev can occur, and if lag dev is NULL a...

CVE-2023-52487

A NULL pointer dereference flaw was found in the Linux kernel, which affects the net/mlx5e component and may occur when a peer flow is not removed from the peer flows list because a concurrent user holds a reference to it. This can cause a NULL pointer dereference when attempting to remove the fl...

CVE-2023-52487

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix peer flow lists handling The cited change refactored mlx5etcdelfdbpeerflow to only clear DUP flag when list of peer flows has become empty. However, if any concurrent user holds a reference to a peer flow for...

Stack overflow

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Wrap the tx reporter dump callback to extract the sq Function mlx5etxreporterdumpsq casts its void argument to struct mlx5etxqsq , but in TX-timeout-recovery flow the argument is actually of type struct mlx5etxtimeoutc...

CVE-2021-46931

CVE-2021-46931 involves the Linux kernel mlx5e path (net/mlx5e, mlx5_core) where a TX-timeout-recovery flow calls mlx5e_tx_reporter_dump_sq() with a void* that is actually a mlx5e_tx_timeout_ctx*. The mismatch corrupts stack state and can trigger a kernel panic/stack overflow. The fix adds a wrap...
