The armv8_dec_aes_gcm_full() API of Arm AArch64cryptolib before 86065c6 fails to the verify the authentication tag of AES-GCM protected data, leading to a man-in-the-middle attack. This occurs because of an improperly initialized variable.
An issue was discovered in the Arm Mali GPU Kernel Driver. A non-privileged user can make improper GPU processing operations to gain access to already freed memory. This affects Valhall r39p0 through r41p0 before r42p0, and Avalon r41p0 before r42p0.
An issue was discovered in the Arm Mali GPU Kernel Driver. A non-privileged user can make improper GPU processing operations to gain access to already freed memory. This affects Midgard r0p0 through r32p0, Bifrost r0p0 through r41p0 before r42p0, Valhall r19p0 through r41p0 before r42p0, and Avalon r41p0 before r42p0.
Use of a Broken or Risky Cryptographic Algorithm in the function mbedtls_mpi_exp_mod() in lignum.c in Mbed TLS Mbed TLS all versions before 3.0.0, 2.27.0 or 2.16.11 allows attackers with access to precise enough timing and memory access information (typically an untrusted operating system attacking a secure enclave such as SGX or the TrustZone secure world) to recover the private keys used in RSA.
An issue was discovered in the Arm Mali GPU Kernel Driver. There is a use-after-free. A non-privileged user can make improper GPU processing operations to gain access to already freed memory. This affects Midgard r13p0 through r32p0, Bifrost r1p0 through r40p0, and Valhall r19p0 through r40p0.
Trusted Firmware-A through 2.8 has an out-of-bounds read in the X.509 parser for parsing boot certificates. This affects downstream use of get_ext and auth_nvctr. Attackers might be able to trigger dangerous read side effects or obtain sensitive information about microarchitectural state.
The AES instructions on the ARMv8 platform do not have an algorithm that is "intrinsically resistant" to side-channel attacks. NOTE: the vendor reportedly offers the position "while power side channel attacks ... are possible, they are not directly caused by or related to the Arm architecture."
An issue was discovered in Mbed TLS before 2.28.2 and 3.x before 3.3.0. An adversary with access to precise enough information about memory accesses (typically, an untrusted operating system attacking a secure enclave) can recover an RSA private key after observing the victim performing a single private-key operation, if the window size (MBEDTLS_MPI_WINDOW_SIZE) used for the exponentiation is 3 or smaller.
An issue was discovered in Mbed TLS before 2.28.2 and 3.x before 3.3.0. There is a potential heap-based buffer overflow and heap-based buffer over-read in DTLS if MBEDTLS_SSL_DTLS_CONNECTION_ID is enabled and MBEDTLS_SSL_CID_IN_LEN_MAX > 2 * MBEDTLS_SSL_CID_OUT_LEN_MAX.
An issue was discovered in the Arm Mali GPU Kernel Driver. There is a use-after-free. A non-privileged user can make improper GPU processing operations to gain access to already freed memory. This affects Valhall r29p0 through r40P0.
