GHSA-QV5H-FQ2W-C68J

Vulnerability from github – Published: 2022-05-14 01:47 – Updated: 2022-05-14 01:47

Details

The init_new_context function in arch/x86/include/asm/mmu_context.h in the Linux kernel before 4.12.10 does not correctly handle errors from LDT table allocation when forking a new process, allowing a local attacker to achieve a use-after-free or possibly have unspecified other impact by running a specially crafted program. This vulnerability only affected kernels built with CONFIG_MODIFY_LDT_SYSCALL=y.

Severity ?

7.0 (High)
