https://notcve.org/view.php?id=CVE-2024-40921
In the Linux kernel, the following vulnerability has been resolved: net: bridge: mst: pass vlan group directly to br_mst_vlan_set_state Pass the already obtained vlan group pointer to br_mst_vlan_set_state() instead of dereferencing it again. Each caller has already correctly dereferenced it for their context. This change is required for the following suspicious RCU dereference fix. No functional changes intended. • https://git.kernel.org/stable/c/8ca9a750fc711911ef616ceb627d07357b04545e https://git.kernel.org/stable/c/4488617e5e995a09abe4d81add5fb165674edb59 https://git.kernel.org/stable/c/e43dd2b1ec746e105b7db5f9ad6ef14685a615a4 https://git.kernel.org/stable/c/a2b01e65d9ba8af2bb086d3b7288ca53a07249ac https://git.kernel.org/stable/c/09f4337c27f5bdeb8646a6db91488cc2f7d537ff https://git.kernel.org/stable/c/a6cc9e9a651b9861efa068c164ee62dfba68c6ca https://git.kernel.org/stable/c/d2dc02775fc0c4eacaee833a0637e5958884a8e5 https://git.kernel.org/stable/c/36c92936e868601fa1f43da6758cf5580 •

In the Linux kernel, the following vulnerability has been resolved: net: bridge: mst: fix suspicious rcu usage in br_mst_set_state I converted br_mst_set_state to RCU to avoid a vlan use-after-free but forgot to change the vlan group dereference helper.

https://notcve.org/view.php?id=CVE-2024-40919
In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Adjust logging of firmware messages in case of released token in __hwrm_send() In case of token is released due to token->state == BNXT_HWRM_DEFERRED, released token (set to NULL) is used in log messages. This issue is expected to be prevented by HWRM_ERR_CODE_PF_UNAVAILABLE error code. But this error code is returned by recent firmware. So some firmware may not return it. This may lead to NULL pointer dereference. Adjust this issue by adding token pointer check.

https://notcve.org/view.php?id=CVE-2024-40918
In the Linux kernel, the following vulnerability has been resolved: parisc: Try to fix random segmentation faults in package builds PA-RISC systems with PA8800 and PA8900 processors have had problems with random segmentation faults for many years. Systems with earlier processors are much more stable. Systems with PA8800 and PA8900 processors have a large L2 cache which needs per page flushing for decent performance when a large range is flushed. The combined cache in these systems is also more sensitive to non-equivalent aliases than the caches in earlier systems. The majority of random segmentation faults that I have looked at appear to be memory corruption in memory allocated using mmap and malloc. My first attempt at fixing the random faults didn't work. On reviewing the cache code, I realized that there were two issues which the existing code didn't handle correctly. Both relate to cache move-in. • https://git.kernel.org/stable/c/5bf196f1936bf93df31112fbdfb78c03537c07b0 https://git.kernel.org/stable/c/d66f2607d89f760cdffed88b22f309c895a2af20 https://git.kernel.org/stable/c/72d95924ee35c8cd16ef52f912483ee938a34d49 •

https://notcve.org/view.php?id=CVE-2024-40917
In the Linux kernel, the following vulnerability has been resolved: memblock: make memblock_set_node() also warn about use of MAX_NUMNODES On an (old) x86 system with SRAT just covering space above 4Gb: ACPI: SRAT: Node 0 PXM 0 [mem 0x100000000-0xfffffffff] hotplug the commit referenced below leads to this NUMA configuration no longer being refused by a CONFIG_NUMA=y kernel (previously NUMA: nodes only cover 6144MB of your 8185MB e820 RAM. Not used. No NUMA configuration found Faking a node at [mem 0x0000000000000000-0x000000027fffffff] was seen in the log directly after the message quoted above), because of memblock_validate_numa_coverage() checking for NUMA_NO_NODE (only). This in turn led to memblock_alloc_range_nid()'s warning about MAX_NUMNODES triggering, followed by a NULL deref in memmap_init() when trying to access node 64's (NODE_SHIFT=6) node data. To compensate said change, make memblock_set_node() warn on and adjust a passed in value of MAX_NUMNODES, just like various other functions already do. • https://git.kernel.org/stable/c/ff6c3d81f2e86b63a3a530683f89ef393882782a https://git.kernel.org/stable/c/22f742b8f738918f683198a18ec3c691acda14c4 https://git.kernel.org/stable/c/e0eec24e2e199873f43df99ec39773ad3af2bff7 •
