CWE-ID: CWE-476
Exploitation vector: Local access
Exploit availability:
No public exploit available
Vendor: Linux Foundation
Affected software:
Linux kernel
Linux kernel
Detailed vulnerability description
The vulnerability allows a local attacker to cause DoS condition on the target system.
The weakness exists due to NULL pointer dereference in the hash_accept function in crypto/algif_hash.c. A local attacker can trigger use of in-kernel hash algorithms for a socket that has received zero bytes of data and cause a kernel oops.
Successful exploitation of the vulnerability results in denial of service.
