  3. CVE-2024-27048
In the Linux kernel, the following vulnerability has been resolved: wifi: brcm80211: handle pmk_op allocation failure The kzalloc() in brcmf_pmksa_v3_op() will return null if the physical memory has run out. As a result, if we dereference the null value, the null pointer dereference bug will happen. Return -ENOMEM from brcmf_pmksa_v3_op() if kzalloc() fails for pmk_op.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: brcm80211: maneja el error de asignación de pmk_op El kzalloc() en brcmf_pmksa_v3_op() devolverá nulo si la memoria física se ha agotado. Como resultado, si eliminamos la referencia del valor nulo, se producirá el error de desreferencia del puntero nulo. Devuelve -ENOMEM de brcmf_pmksa_v3_op() si kzalloc() falla para pmk_op.
