CVE-2024-35847

Severity CVSS v4.0:
Pending analysis
Type:
CWE-415 Double Free
Publication date:

Last modified:

Description

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