Ubuntu.comUB:CVE-2024-35847CVE-2024-35847
In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v3-its: Prevent double free on error The error handling path in
its_vpe_irq_domain_alloc() causes a double free when its_vpe_init() fails
after successfully allocating at least one interrupt. This happens because
its_vpe_irq_domain_free() frees the interrupts along with the area bitmap
and the vprop_page and its_vpe_irq_domain_alloc() subsequently frees the
area bitmap and the vprop_page again. Fix this by unconditionally invoking
its_vpe_irq_domain_free() which handles all cases correctly and by removing
the bitmap/vprop_page freeing from its_vpe_irq_domain_alloc(). [ tglx:
