Summary
CVE-2024-36477 affecting package kernel for versions less than 6.6.35.1-4
Details

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.
