  3. CVE-2024-47698
In the Linux kernel, the following vulnerability has been resolved: drivers: media: dvb-frontends/rtl2832: fix an out-of-bounds write error Ensure index in rtl2832_pid_filter does not exceed 31 to prevent out-of-bounds access. dev->filters is a 32-bit value, so set_bit and clear_bit functions should only operate on indices from 0 to 31. If index is 32, it will attempt to access a non-existent 33rd bit, leading to out-of-bounds access. Change the boundary check from index > 32 to index >= 32 to resolve this issue. [hverkuil: added fixes tag, rtl2830_pid_filter -> rtl2832_pid_filter in logmsg]

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drivers: media: dvb-frontends/rtl2832: corrige un error de escritura fuera de los límites Asegúrate de que el índice en rtl2832_pid_filter no supere 31 para evitar el acceso fuera de los límites. dev->filters es un valor de 32 bits, por lo que las funciones set_bit y clear_bit solo deben funcionar en índices de 0 a 31. Si el índice es 32, intentará acceder a un bit 33 inexistente, lo que provocará un acceso fuera de los límites. Cambia la comprobación de límites de índice > 32 a índice >= 32 para resolver este problema. [hverkuil: se agregó la etiqueta de correcciones, rtl2830_pid_filter -> rtl2832_pid_filter en logmsg]
