In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Use mlx5_ipsec_rx_status_destroy to correctly delete status rules rx_create no longer allocates a modify_hdr instance that needs to be cleaned up. The mlx5_modify_header_dealloc call will lead to a NULL pointer dereference. A leak in the rules also previously occurred since there are now two rules populated related to status.

https://notcve.org/view.php?id=CVE-2024-36244
In the Linux kernel, the following vulnerability has been resolved: net/sched: taprio: extend minimum interval restriction to entire cycle too It is possible for syzbot to side-step the restriction imposed by the blamed commit in the Fixes: tag, because the taprio UAPI permits a cycle-time different from (and potentially shorter than) the sum of entry intervals. We need one more restriction, which is that the cycle time itself must be larger than N * ETH_ZLEN bit times, where N is the number of schedule entries. This restriction needs to apply regardless of whether the cycle time came from the user or was the implicit, auto-calculated value, so we move the existing "cycle == 0" check outside the "if "(!new->cycle_time)" branch. This way covers both conditions and scenarios. Add a selftest which illustrates the issue triggered by syzbot. • https://git.kernel.org/stable/c/b5b73b26b3ca34574124ed7ae9c5ba8391a7f176 https://git.kernel.org/stable/c/83bd58952b2b8543d8c48d1453975ab47a0a7504 https://git.kernel.org/stable/c/817ff50796c5e364c879596509f83fcba194bb6f https://git.kernel.org/stable/c/34d83c3e6e97867ae061d14eb52123404aab1cbc https://git.kernel.org/stable/c/b939d1e04a90248b4cdf417b0969c270ceb992b2 https://git.kernel.org/stable/c/91f249b01fe490fce11fbb4307952ca8cce78724 https://git.kernel.org/stable/c/fb66df20a7201e60f2b13d7f95d031b31a8831d3 https://access.redhat.com/security/cve/CVE-2024-36244 • CWE-20: Improper Input Validation •
