Out-of-bounds

The eBPF ALU32 bounds tracking for bitwise ops AND, OR and XOR in the Linux kernel did not properly update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and therefore, arbitrary code execution. This issue was fixed via commit 049c4e13714e "bpf: Fix...

CVE-2021-3491

The iouring subsystem in the Linux kernel allowed the MAXRWCOUNT limit to be bypassed in the PROVIDEBUFFERS operation, which led to negative values being usedin memrw when reading /proc//mem. This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was...

GHSA-8RM6-75MF-7R7R Division by zero in TFLite's implementation of hashtable lookup

Impact The TFLite implementation of hashtable lookup is vulnerable to a division by zero error: cc const int numrows = SizeOfDimensionvalue, 0; const int rowbytes = value-bytes / numrows; An attacker can craft a model such that values's first dimension would be 0. Patches We have patched the issu...
