CVE-2023-53435 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: cassini: Fix a memory leak in the error handling path of cas_init_one() cas_saturn_firmware_init() allocates some memory using vmalloc(). This memory is freed in the .remove() function but not it the error handling path of the probe. Add the missing vfree() to avoid a memory leak, should an error occur.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
