kernel: zram: fix NULL pointer in comp_algorithm_show()

A flaw was found in the Linux kernel's zram driver. This vulnerability can lead to a Denial of Service DoS by causing a system crash. During device initialization, a timing window allows a local user to access the device attributes through the sysfs interface before compression algorithms are...

kernel: zram: free secondary algorithms names

A flaw was found in the zram component of the Linux kernel. When a zram device with multiple streams is reset, the secondary algorithm names are not properly freed. This oversight leads to a memory leak, which a local attacker could potentially exploit to cause a Denial of Service DoS by exhausti...
