GSD-2021-1002157 mlxsw: thermal: Fix out-of-bounds memory accesses

mlxsw: thermal: Fix out-of-bounds memory accesses This is an automated ID intended to aid in discovery of potential security vulnerabilities. The actual impact and attack plausibility have not yet been proven. This ID is fixed in Linux Kernel version v5.15 by commit...

kernel: protection for sequences of pointer arithmetic operations against speculatively out-of-bounds loads can be bypassed to leak content of kernel memory

A vulnerability was discovered in retrieveptrlimit in kernel/bpf/verifier.c in the Linux kernel mechanism to mitigate speculatively out-of-bounds loads Spectre mitigation. In this flaw a local, special user privileged CAPSYSADMIN BPF program running on affected systems may bypass the protection,...

kernel: net: qrtr: Fix an uninit variable access bug in qrtr_tx_resume()

An uninitialized memory access flaw was found in the Linux kernel's QRTR Qualcomm IPC Router protocol in the transmit resume handling. When processing RESUMETX messages, if the packet size is smaller than the expected control structure, the qrtrtxresume function reads uninitialized memory from th...

kernel: protection of stack pointer against speculative pointer arithmetic can be bypassed to leak content of kernel memory

A flaw was found in the Linux kernel's eBPF verification code. By default, accessing the eBPF verifier is only accessible to privileged users with CAPSYSADMIN. This flaw allows a local user who can insert eBPF instructions, to use the eBPF verifier to abuse a spectre-like flaw and infer all syste...
