CVE-2024-35908

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: tls: obtenga referencia de psock después de tomar rxlock para evitar fugas. Al inicio de tls_sw_recvmsg, tomamos una referencia en psock y luego llamamos a tls_rx_reader_lock. Si eso falla, volvemos directamente sin liberar la referencia. En lugar de agregar una nueva etiqueta, simplemente tome la referencia después de que el bloqueo se haya realizado correctamente, ya que no la necesitamos antes.

In the Linux kernel, the following vulnerability has been resolved: tls: get psock ref after taking rxlock to avoid leak At the start of tls_sw_recvmsg, we take a reference on the psock, and then call tls_rx_reader_lock. If that fails, we return directly without releasing the reference. Instead of adding a new label, just take the reference after locking has succeeded, since we don't need it before.

It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when modifying certain settings values through debugfs. A privileged local attacker could use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
