Descriptions

In the Linux kernel, the following vulnerability has been resolved: PM / devfreq: Fix buffer overflow in trans_stat_show Fix buffer overflow in trans_stat_show(). Convert simple snprintf to the more secure scnprintf with size of
PAGE_SIZE. Add condition checking if we are exceeding PAGE_SIZE and exit early from
loop. Also add at the end a warning that we exceeded PAGE_SIZE and that
stats is disabled. Return -EFBIG in the case where we don't have enough space to write the
full transition table. Also document in the ABI that this function can return -EFBIG error.

En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: PM / devfreq: Arreglar desbordamiento de búfer en trans_stat_show Arreglar desbordamiento de búfer en trans_stat_show(). Convierta snprintf simple en scnprintf más seguro con un tamaño de PAGE_SIZE. Agregue verificación de condiciones si excedemos PAGE_SIZE y salga temprano del ciclo. También agregue al final una advertencia de que excedimos PAGE_SIZE y que las estadísticas están deshabilitadas. Devuelve -EFBIG en el caso de que no tengamos suficiente espacio para escribir la tabla de transición completa. También documente en la ABI que esta función puede devolver el error -EFBIG.

Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly validate H2C PDU data, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a denial of service. Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida discovered that the Linux kernel mitigations for the initial Branch History Injection vulnerability were insufficient for Intel processors. A local attacker could potentially use this to expose sensitive information.
