CVE-2024-40903

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: typec: tcpm: arreglar el caso de use-after-free en tcpm_register_source_caps Podría haber un posible caso de use-after-free en tcpm_register_source_caps(). Esto podría suceder cuando: * se anuncian límites de fuente nuevos (por ejemplo, no válidos) * los límites de fuente existentes no están registrados * tcpm_register_source_caps() devuelve un error ya que usb_power_delivery_register_capabilities() falla Esto hace que port->partner_source_caps conserve los límites de fuente ahora liberados. Restablezca el valor de puerto->partner_source_caps a NULL después de cancelar el registro de los límites de origen existentes.

A vulnerability was found in the tcpm_register_source_caps function in the Linux kernel's USB Type-C TCPM component. This issue arises when new, potentially invalid source capabilities are advertised while existing capabilities are unregistered, leading to a use-after-free condition if the registration fails.

In the Linux kernel, the following vulnerability has been resolved: usb: typec: tcpm: fix use-after-free case in tcpm_register_source_caps There could be a potential use-after-free case in tcpm_register_source_caps(). This could happen when: * new (say invalid) source caps are advertised * the existing source caps are unregistered * tcpm_register_source_caps() returns with an error as usb_power_delivery_register_capabilities() fails This causes port->partner_source_caps to hold on to the now freed source caps. Reset port->partner_source_caps value to NULL after unregistering existing source caps.

Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the JFS file system contained an out-of-bounds read vulnerability when printing xattr debug information. A local attacker could use this to cause a denial of service.
