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 • CWE-125: Out-of-bounds Read •
