https://notcve.org/view.php?id=CVE-2024-40989
In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Disassociate vcpus from redistributor region on teardown When tearing down a redistributor region, make sure we don't have any dangling pointer to that region stored in a vcpu. A vulnerability was found in the Linux kernel's KVM for ARM64 within the vgic-init.c, vgic-mmio-v3.c, and vgic.h files. The virtual vCPUs may retain dangling pointers in a redistributor region after they have been torn down, leading to potential memory corruption. • https://git.kernel.org/stable/c/e5a35635464bc5304674b84ea42615a3fd0bd949 https://git.kernel.org/stable/c/68df4fc449fcc24347209e500ce26d5816705a77 https://git.kernel.org/stable/c/48bb62859d47c5c4197a8c01128d0fa4f46ee58c https://git.kernel.org/stable/c/152b4123f21e6aff31cea01158176ad96a999c76 https://git.kernel.org/stable/c/0d92e4a7ffd5c42b9fa864692f82476c0bf8bcc8 https://access.redhat.com/security/cve/CVE-2024-40989 https://bugzilla.redhat.com/show_bug.cgi?id=2297573 • CWE-825: Expired Pointer Dereference •

https://notcve.org/view.php?id=CVE-2024-40984
In the Linux kernel, the following vulnerability has been resolved: ACPICA: Revert "ACPICA: avoid Info: mapping multiple BARs. Your kernel is fine." Undo the modifications made in commit d410ee5109a1 ("ACPICA: avoid "Info: mapping multiple BARs. Your kernel is fine.""). The initial purpose of this commit was to stop memory mappings for operation regions from overlapping page boundaries, as it can trigger warnings if different page attributes are present. However, it was found that when this situation arises, mapping continues until the boundary's end, but there is still an attempt to read/write the entire length of the map, leading to a NULL pointer deference. • https://git.kernel.org/stable/c/d410ee5109a1633a686a5663c6743a92e1181f9b https://git.kernel.org/stable/c/435ecc978c3d5d0c4e172ec5b956dc1904061d98 https://git.kernel.org/stable/c/ae465109d82f4fb03c5adbe85f2d6a6a3d59124c https://git.kernel.org/stable/c/6eca23100e9030725f69c1babacd58803f29ec8d https://git.kernel.org/stable/c/dc5017c57f5eee80020c73ff8b67ba7f9fd08b1f https://git.kernel.org/stable/c/ddc1f5f124479360a1fd43f73be950781d172239 https://git.kernel.org/stable/c/434c6b924e1f4c219aab2d9e05fe79c5364e37d3 https://git.kernel.org/stable/c/e21a4c9129c72fa54dd00f5ebf71219b4 • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2024-40983
In the Linux kernel, the following vulnerability has been resolved: tipc: force a dst refcount before doing decryption As it says in commit 3bc07321ccc2 ("xfrm: Force a dst refcount before entering the xfrm type handlers"): "Crypto requests might return asynchronous. In this case we leave the rcu protected region, so force a refcount on the skb's destination entry before we enter the xfrm type input/output handlers." On TIPC decryption path it has the same problem, and skb_dst_force() should be called before doing decryption to avoid a possible crash.
