CVE-2022-50495 Details
Description
Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
A memory leak vulnerability has been identified in the Linux kernel's handling of Xen symmetric multiprocessing (SMP) interrupts. This issue arises in the 'xen_smp_intr_init' function, where local variables intended to store interrupt names are not properly managed. When the function 'bind_ipi_to_irqhandler' fails, the allocated names are not saved, leading to a memory leak. The problem has been addressed by ensuring that these names are correctly freed. This vulnerability affects the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel stable tree, where this vulnerability has been fixed. Instructions for downloading the patched version are available on the Linux kernel official website.
