CVE-2022-49619
Last modified
CVE-2022-49619 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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().. EPSS estimates a 0.24% chance of exploitation in the next 30 days.
