https://notcve.org/view.php?id=CVE-2024-38663
In the Linux kernel, the following vulnerability has been resolved: blk-cgroup: fix list corruption from resetting io stat Since commit 3b8cc6298724 ("blk-cgroup: Optimize blkcg_rstat_flush()"), each iostat instance is added to blkcg percpu list, so blkcg_reset_stats() can't reset the stat instance by memset(), otherwise the llist may be corrupted. Fix the issue by only resetting the counter part. • https://git.kernel.org/stable/c/3b8cc6298724021da845f2f9fd7dd4b6829a6817 https://git.kernel.org/stable/c/d4a60298ac34f027a09f8f893fdbd9e06279bb24 https://git.kernel.org/stable/c/89bb36c72e1951843f9e04dc84412e31fcc849a9 https://git.kernel.org/stable/c/6da6680632792709cecf2b006f2fe3ca7857e791 https://access.redhat.com/security/cve/CVE-2024-38663 https://bugzilla.redhat.com/show_bug.cgi?id=2294225 • CWE-665: Improper Initialization •

https://notcve.org/view.php?id=CVE-2024-38384
In the Linux kernel, the following vulnerability has been resolved: blk-cgroup: fix list corruption from reorder of WRITE ->lqueued __blkcg_rstat_flush() can be run anytime, especially when blk_cgroup_bio_start is being executed. If WRITE of `->lqueued` is re-ordered with READ of 'bisc->lnode.next' in the loop of __blkcg_rstat_flush(), `next_bisc` can be assigned with one stat instance being added in blk_cgroup_bio_start(), then the local list in __blkcg_rstat_flush() could be corrupted. Fix the issue by adding one barrier. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: blk-cgroup: corrupción de la lista de arreglos debido al reordenamiento de WRITE ->lqueued __blkcg_rstat_flush() se puede ejecutar en cualquier momento, especialmente cuando se está ejecutando blk_cgroup_bio_start. Si la ESCRITURA de `->lqueued` se reordena con la READ de 'bisc->lnode.next' en el bucle de __blkcg_rstat_flush(), se puede asignar `next_bisc` agregando una instancia de estadística en blk_cgroup_bio_start(), entonces el La lista local en __blkcg_rstat_flush() podría estar dañada.

In the Linux kernel, the following vulnerability has been resolved: tracing/probes: fix error check in parse_btf_field() btf_find_struct_member() might return NULL or an error via the ERR_PTR() macro. However, its caller in parse_btf_field() only checks for the NULL condition. Fix this by using IS_ERR() and returning the error up the stack.

https://notcve.org/view.php?id=CVE-2024-36477
In the Linux kernel, the following vulnerability has been resolved: tpm_tis_spi: Account for SPI header when allocating TPM SPI xfer buffer The TPM SPI transfer mechanism uses MAX_SPI_FRAMESIZE for computing the maximum transfer length and the size of the transfer buffer. As such, it does not account for the 4 bytes of header that prepends the SPI data frame. This can result in out-of-bounds accesses and was confirmed with KASAN. Introduce SPI_HDRSIZE to account for the header and use to allocate the transfer buffer. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tpm_tis_spi: Cuenta para el encabezado SPI al asignar el búfer de transferencia TPM SPI El mecanismo de transferencia TPM SPI utiliza MAX_SPI_FRAMESIZE para calcular la longitud máxima de transferencia y el tamaño del búfer de transferencia. Como tal, no tiene en cuenta los 4 bytes del encabezado que antepone el marco de datos SPI. • https://git.kernel.org/stable/c/a86a42ac2bd652fdc7836a9d880c306a2485c142 https://git.kernel.org/stable/c/1547183852dcdfcc25878db7dd3620509217b0cd https://git.kernel.org/stable/c/de13c56f99477b56980c7e00b09c776d16b7563d https://git.kernel.org/stable/c/195aba96b854dd664768f382cd1db375d8181f88 https://access.redhat.com/security/cve/CVE-2024-36477 https://bugzilla.redhat.com/show_bug.cgi?id=2293639 • CWE-125: Out-of-bounds Read •
