USN-8576-1: Linux kernel (NVIDIA Tegra) vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...

CVE-2023-20588 Speculative Leaks

A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality...

Medium: kernel

Issue Overview: An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flushtoldisc function. This flaw allows a local user...

UBUNTU-CVE-2021-29155

An issue was discovered in the Linux kernel through 5.11.x. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory. Specifically, for sequences ...

An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c has an off-by-one error (with a resultant integer underflow) affecting out-of-bounds speculation on pointer arithmetic leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory aka CID-10d2bb2e6b1d.
