CVE-2024-26945

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: crypto: iaa - Corrige el caso nr_cpus < nr_iaa Si nr_cpus < nr_iaa, el cpus_per_iaa calculado será 0, lo que provoca una división por 0 en rebalance_wq_table(). Asegúrese de que cpus_per_iaa sea 1 en ese caso, y también en el caso de nr_iaa == 0, aunque cpus_per_iaa nunca se use si nr_iaa == 0, para paranoia.

In the Linux kernel, the following vulnerability has been resolved: crypto: iaa - Fix nr_cpus < nr_iaa case If nr_cpus < nr_iaa, the calculated cpus_per_iaa will be 0, which causes a divide-by-0 in rebalance_wq_table(). Make sure cpus_per_iaa is 1 in that case, and also in the nr_iaa == 0 case, even though cpus_per_iaa is never used if nr_iaa == 0, for paranoia.

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.
