CVE-2024-26930

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: qla2xxx: Corrección de doble liberación del puntero ha->vp_map Coverity scan informó un riesgo potencial de doble liberación del puntero ha->vp_map. ha->vp_map se liberó en qla2x00_mem_alloc() y nuevamente se liberó en la función qla2x00_mem_free(ha). Asigne NULL a vp_map y kfree se encargará de NULL.

A vulnerability was found in the Linux kernel. A potential double-free in the pointer ha->vp_map exists in the Linux kernel in drivers/scsi/qla2xxx/qla_os.c.

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix double free of the ha->vp_map pointer Coverity scan reported potential risk of double free of the pointer ha->vp_map. ha->vp_map was freed in qla2x00_mem_alloc(), and again freed in function qla2x00_mem_free(ha). Assign NULL to vp_map and kfree take care of NULL.

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service.
