In the Linux kernel, the following vulnerability has been resolved: tracing: Fix overflow in get_free_elt() "tracing_map->next_elt" in get_free_elt() is at risk of overflowing. Once it overflows, new elements can still be inserted into the tracing_map even though the maximum number of elements (`max_elts`) has been reached. Continuing to insert elements after the overflow could result in the tracing_map containing "tracing_map->max_size" elements, leaving no empty entries. If any attempt is made to insert an element into a full tracing_map using `__tracing_map_insert()`, it will cause an infinite loop with preemption disabled, leading to a CPU hang problem. Fix this by preventing any further increments to "tracing_map->next_elt" once it reaches "tracing_map->max_elt". • https://git.kernel.org/stable/c/08d43a5fa063e03c860f2f391a30c388bcbc948e https://git.kernel.org/stable/c/302ceb625d7b990db205a15e371f9a71238de91c https://git.kernel.org/stable/c/d3e4dbc2858fe85d1dbd2e72a9fc5dea988b5c18 https://git.kernel.org/stable/c/eb223bf01e688dfe37e813c8988ee11c8c9f8d0a https://git.kernel.org/stable/c/cd10d186a5409a1fe6e976df82858e9773a698da https://git.kernel.org/stable/c/788ea62499b3c18541fd6d621964d8fafbc4aec5 https://git.kernel.org/stable/c/a172c7b22bc2feaf489cfc6d6865f7237134fdf8 https://git.kernel.org/stable/c/236bb4690773ab6869b40bedc7bc8d889 •

In the Linux kernel, the following vulnerability has been resolved: padata: Fix possible divide-by-0 panic in padata_mt_helper() We are hit with a not easily reproducible divide-by-0 panic in padata.c at bootup time.

The way that chunk_size is initialized in padata_do_multithreaded(), chunk_size can be 0 when the min_chunk in the passed-in padata_mt_job structure is 0. Fix this divide-by-0 panic by making sure that chunk_size will be at least 1 no matter what the input parameters are. A denial of service vulnerability exists in the Linux kernel. A possible divide-by-0 is in the padata_mt_helper() function when the ps->chunk_size is 0. • https://git.kernel.org/stable/c/004ed42638f4428e70ead59d170f3d17ff761a0f https://git.kernel.org/stable/c/ab8b397d5997d8c37610252528edc54bebf9f6d3 https://git.kernel.org/stable/c/8f5ffd2af7274853ff91d6cd62541191d9fbd10d https://git.kernel.org/stable/c/a29cfcb848c31f22b4de6a531c3e1d68c9bfe09f https://git.kernel.org/stable/c/924f788c906dccaca30acab86c7124371e1d6f2c https://git.kernel.org/stable/c/da0ffe84fcc1627a7dff82c80b823b94236af905 https://git.kernel.org/stable/c/6d45e1c948a8b7ed6ceddb14319af69424db730c https://access.redhat.com/security/cve/CVE-2024-43889 • CWE-369: Divide By Zero •

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add null check in resource_log_pipe_topology_update [WHY] When switching from "Extend" to "Second Display Only" we sometimes call resource_get_otg_master_for_stream on a stream for the eDP, which is disconnected. This leads to a null pointer dereference. [HOW] Added a null check in dc_resource.c/resource_log_pipe_topology_update. • https://git.kernel.org/stable/c/c36e922a36bdf69765c340a0857ca74092003bee https://git.kernel.org/stable/c/899d92fd26fe780aad711322aa671f68058207a6 •

In the Linux kernel, the following vulnerability has been resolved: usb: vhci-hcd: Do not drop references before new references are gained At a few places the driver carries stale pointers to references that can still be used. Make sure that does not happen. This strictly speaking closes ZDI-CAN-22273, though there may be similar races in the driver. • https://git.kernel.org/stable/c/5a3c473b28ae1c1f7c4dc129e30cb19ae6e96f89 https://git.kernel.org/stable/c/9c3746ce8d8fcb3a2405644fc0eec7fc5312de80 https://git.kernel.org/stable/c/4dacdb9720aaab10b6be121eae55820174d97174 https://git.kernel.org/stable/c/e8c1e606dab8c56cf074b43b98d0805de7322ba2 https://git.kernel.org/stable/c/585e6bc7d0a9bf73a8be3d3fb34e86b90cc61a14 https://git.kernel.org/stable/c/128e82e41cf7d74a562726c1587d9d2ede1a0a37 https://git.kernel.org/stable/c/c3d0857b7fc2c49f68f89128a5440176089a8f54 https://git.kernel.org/stable/c/afdcfd3d6fcdeca2735ca8d994c5f2d24 •
