CVE-2024-26839

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: IB/hfi1: corrige una fuga de mem en init_credit_return Cuando dma_alloc_coherent no puede asignar dd->cr_base[i].va, init_credit_return debería desasignar dd->cr_base y dd->cr_base[i]. ] el asignado antes. O esos recursos nunca se liberarían y se desencadenaría una fuga de memoria.

In the Linux kernel, the following vulnerability has been resolved: IB/hfi1: Fix a memleak in init_credit_return When dma_alloc_coherent fails to allocate dd->cr_base[i].va, init_credit_return should deallocate dd->cr_base and dd->cr_base[i] that allocated before. Or those resources would be never freed and a memleak is triggered.

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. It was discovered that the ATA over Ethernet driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code.
