CVE-2024-39489

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ipv6: sr: corrige memleak en seg6_hmac_init_algo seg6_hmac_init_algo regresa sin limpiar las asignaciones anteriores si una falla, por lo que perderá toda esa memoria y los tfms criptográficos. Actualice seg6_hmac_exit para liberar solo la memoria cuando esté asignada, de modo que podamos reutilizar el código directamente.

In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix memleak in seg6_hmac_init_algo seg6_hmac_init_algo returns without cleaning up the previous allocations if one fails, so it's going to leak all that memory and the crypto tfms. Update seg6_hmac_exit to only free the memory when allocated, so we can reuse the code directly.

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. Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service.
