GHSA-5M26-PCQQ-27H8
Vulnerability from github – Published: 2025-10-04 18:31 – Updated: 2025-10-04 18:31In the Linux kernel, the following vulnerability has been resolved:
x86/xen: Fix memory leak in xen_smp_intr_init{_pv}()
These local variables @{resched|pmu|callfunc...}name saves the new string allocated by kasprintf(), and when bind{v}ipi_to_irqhandler() fails, it goes to the @fail tag, and calls xen_smp_intr_free{_pv}() to free resource, however the new string is not saved, which cause a memory leak issue. fix it.
