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. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: rastreo/sondas: corrección de verificación de errores en parse_btf_field() btf_find_struct_member() puede devolver NULL o un error a través de la macro ERR_PTR(). Sin embargo, su llamador en parse_btf_field() solo verifica la condición NULL. • https://git.kernel.org/stable/c/c440adfbe30257dde905adc1fce51131145f7245 https://git.kernel.org/stable/c/ad4b202da2c498fefb69e5d87f67b946e7fe1e6a https://git.kernel.org/stable/c/4ed468edfeb54c7202e559eba74c25fac6a0dad0 https://git.kernel.org/stable/c/e569eb34970281438e2b48a3ef11c87459fcfbcb • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVSS: 7.8EPSS: 0%CPEs: 3EXPL: 0CVE-2024-36477 – tpm_tis_spi: Account for SPI header when allocating TPM SPI xfer buffer
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 •
