In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: Add some bounds checking to firmware data Smatch complains about "head->full_size - head->header_size" can underflow. To some extent, we're always going to have to trust the firmware a bit. However, it's easy enough to add a check for negatives, and let's add a upper bounds check as well.

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-26926 – binder: check offset alignment in binder_get_object()
https://notcve.org/view.php?id=CVE-2024-26926
In the Linux kernel, the following vulnerability has been resolved: binder: check offset alignment in binder_get_object() Commit 6d98eb95b450 ("binder: avoid potential data leakage when copying txn") introduced changes to how binder objects are copied. In doing so, it unintentionally removed an offset alignment check done through calls to binder_alloc_copy_from_buffer() -> check_buffer(). These calls were replaced in binder_get_object() with copy_from_user(), so now an explicit offset alignment check is needed here. This avoids later complications when unwinding the objects gets harder. It is worth noting this check existed prior to commit 7a67a39320df ("binder: add function to copy binder object from buffer"), likely removed due to redundancy at the time. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Binder: verifique la alineación de desplazamiento en binder_get_object() El commit 6d98eb95b450 ("binder: evite posibles fugas de datos al copiar txn") introdujo cambios en la forma en que se copian los objetos de Binder. Al hacerlo, eliminó involuntariamente una verificación de alineación de desplazamiento realizada mediante llamadas a binder_alloc_copy_from_buffer() -> check_buffer(). • https://git.kernel.org/stable/c/c056a6ba35e00ae943e377eb09abd77a6915b31a https://git.kernel.org/stable/c/23e9d815fad84c1bee3742a8de4bd39510435362 https://git.kernel.org/stable/c/7a9ad4aceb0226b391c9d3b8e4ac2e7d438b6bde https://git.kernel.org/stable/c/6d98eb95b450a75adb4516a1d33652dc78d2b20c https://git.kernel.org/stable/c/66e12f5b3a9733f941893a00753b10498724607d https://git.kernel.org/stable/c/68a28f551e4690db2b27b3db716c7395f6fada12 https://git.kernel.org/stable/c/48a1f83ca9c68518b1a783c62e6a8223144fa9fc https://git.kernel.org/stable/c/a2fd6dbc98be1105a1d8e9e31575da887 •
CVSS: 7.0EPSS: 0%CPEs: 9EXPL: 0CVE-2024-26925 – netfilter: nf_tables: release mutex after nft_gc_seq_end from abort path
https://notcve.org/view.php?id=CVE-2024-26925
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: release mutex after nft_gc_seq_end from abort path The commit mutex should not be released during the critical section between nft_gc_seq_begin() and nft_gc_seq_end(), otherwise, async GC worker could collect expired objects and get the released commit lock within the same GC sequence. nf_tables_module_autoload() temporarily releases the mutex to load module dependencies, then it goes back to replay the transaction again. Move it at the end of the abort phase after nft_gc_seq_end() is called. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: netfilter: nf_tables: libera mutex después de nft_gc_seq_end de la ruta de cancelación. El mutex de confirmación no debe liberarse durante la sección crítica entre nft_gc_seq_begin() y nft_gc_seq_end(); de lo contrario, el trabajador asíncrono de GC podría recopilar objetos caducados y obtener el bloqueo de confirmación liberado dentro de la misma secuencia de GC. nf_tables_module_autoload() libera temporalmente el mutex para cargar las dependencias del módulo, luego vuelve a reproducir la transacción nuevamente. Muévalo al final de la fase de cancelación después de llamar a nft_gc_seq_end(). A flaw was found in the Linux kernel’s Netfilter nf_tables module. • https://git.kernel.org/stable/c/4b6346dc1edfb9839d6edee7360ed31a22fa6c95 https://git.kernel.org/stable/c/23292bdfda5f04e704a843b8f97b0eb95ace1ca6 https://git.kernel.org/stable/c/b44a459c6561595ed7c3679599c5279204132b33 https://git.kernel.org/stable/c/5d319f7a81431c6bb32eb4dc7d7975f99e2c8c66 https://git.kernel.org/stable/c/720344340fb9be2765bbaab7b292ece0a4570eae https://git.kernel.org/stable/c/f85ca36090cbb252bcbc95fc74c2853fc792694f https://git.kernel.org/stable/c/e07e68823116563bdbc49cef185cda6f463bc534 https://git.kernel.org/stable/c/61ac7284346c32f9a8c8ceac56102f791 • CWE-667: Improper Locking •
