  2. Vulnerabilities (CVE)
  3. CVE-2022-49619
In the Linux kernel, the following vulnerability has been resolved: net: sfp: fix memory leak in sfp_probe() sfp_probe() allocates a memory chunk from sfp with sfp_alloc(). When devm_add_action() fails, sfp is not freed, which leads to a memory leak. We should use devm_add_action_or_reset() instead of devm_add_action().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: sfp: se corrige la pérdida de memoria en sfp_probe() sfp_probe() asigna un fragmento de memoria de sfp con sfp_alloc(). Cuando devm_add_action() falla, sfp no se libera, lo que provoca una pérdida de memoria. Deberíamos utilizar devm_add_action_or_reset() en lugar de devm_add_action().
