  2. Vulnerabilities (CVE)
  3. CVE-2022-49748
In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd: fix potential integer overflow on shift of a int The left shift of int 32 bit integer constant 1 is evaluated using 32 bit arithmetic and then passed as a 64 bit function argument. In the case where i is 32 or more this can lead to an overflow. Avoid this by shifting using the BIT_ULL macro instead.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: perf/x86/amd: se corrige un posible desbordamiento de enteros al desplazar un entero. El desplazamiento a la izquierda de la constante entera de 32 bits 1 se evalúa mediante aritmética de 32 bits y se pasa como argumento de función de 64 bits. Si i es 32 o más, esto puede provocar un desbordamiento. Para evitarlo, utilice la macro BIT_ULL para desplazar.
