CVE-2024-26674

CVE-2024-26674 affects the Linux kernel x86/mm code, specifically a fixup path for get_user()/put_user(). In kernel builds >= 6.4 memory-error-injection can trigger a machine-check and panic due to a revert from _ASM_EXTABLE_UA() to a more generic fixup type. The issue arose when MCA handling ...

CVE-2023-0459

A vulnerability was found in copyfromuser in 64-bit versions of the Linux kernel. This flaw allows a local attacker to bypass the "accessok" sanity check and pass a kernel pointer to copyfromuser, resulting in kernel data leaking. Mitigation Mitigation for this issue is either not available or th...
