https://notcve.org/view.php?id=CVE-2022-48883
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: IPoIB, Block PKEY interfaces with less rx queues than parent A user is able to configure an arbitrary number of rx queues when creating an interface via netlink. This doesn't work for child PKEY interfaces because the child interface uses the parent receive channels. Although the child shares the parent's receive channels, the number of rx queues is important for the channel_stats array: the parent's rx channel index is used to access the child's channel_stats. So the array has to be at least as large as the parent's rx queue size for the counting to work correctly and to prevent out of bound accesses. This patch checks for the mentioned scenario and returns an error when trying to create the interface. The error is propagated to the user. • https://git.kernel.org/stable/c/be98737a4faa3a0dc1781ced5bbf5c47865e29d7 https://git.kernel.org/stable/c/5844a46f09f768da866d6b0ffbf1a9073266bf24 https://git.kernel.org/stable/c/31c70bfe58ef09fe36327ddcced9143a16e9e83d https://access.redhat.com/security/cve/CVE-2022-48883 https://bugzilla.redhat.com/show_bug.cgi?id=2306404 • CWE-130: Improper Handling of Length Parameter Inconsistency •

https://notcve.org/view.php?id=CVE-2022-48882
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix macsec possible null dereference when updating MAC security entity (SecY) Upon updating MAC security entity (SecY) in hw offload path, the macsec security association (SA) initialization routine is called. In case of extended packet number (epn) is enabled the salt and ssci attributes are retrieved using the MACsec driver rx_sa context which is unavailable when updating a SecY property such as encoding-sa hence the null dereference. Fix by using the provided SA to set those attributes. • https://git.kernel.org/stable/c/4411a6c0abd3e55b4a4fb9432b3a0553f12337c2 https://git.kernel.org/stable/c/514d9c6a39213d8200884e70f60ce7faef1ee597 https://git.kernel.org/stable/c/9828994ac492e8e7de47fe66097b7e665328f348 •

In the Linux kernel, the following vulnerability has been resolved: platform/surface: aggregator: Add missing call to ssam_request_sync_free() Although rare, ssam_request_sync_init() can fail. In that case, the request should be freed via ssam_request_sync_free(). Currently it is leaked instead.

In the Linux kernel, the following vulnerability has been resolved: efi: fix NULL-deref in init error path In cases where runtime services are not supported or have been disabled, the runtime services workqueue will never have been allocated. Do not try to destroy the workqueue unconditionally in the unlikely event that EFI initialisation fails to avoid dereferencing a NULL pointer. • https://git.kernel.org/stable/c/2ff3c97b47521d6700cc6485c7935908dcd2c27c https://git.kernel.org/stable/c/5167f194da6947e19a3e970485ee3ccb44f7958d https://git.kernel.org/stable/c/98086df8b70c06234a8f4290c46064e44dafa0ed https://git.kernel.org/stable/c/f591a42b8f9a9d20e01d0462f4f55d2176ac52ec https://git.kernel.org/stable/c/e6584124b9823151ef586d10dedf565ade50cea6 https://git.kernel.org/stable/c/585a0b2b3ae7903c6abee3087d09c69e955a7794 https://git.kernel.org/stable/c/5fcf75a8a4c3e7ee9122d143684083c9faf20452 https://git.kernel.org/stable/c/4ca71bc0e1995d15486cd7b60845602a2 •
