Kerentanan Missing Release of Memory after Effective Lifetime pada linux kernel. Skor CVSS 3.1 5.5 (Medium) menurut NVD.

Deskripsi (NVD)

In the Linux kernel, the following vulnerability has been resolved: nfsd: call op_release, even when op_func returns an error For ops with "trivial" replies, nfsd4_encode_operation will shortcut most of the encoding work and skip to just marshalling up the status. One of the things it skips is calling op_release. This could cause a memory leak in the layoutget codepath if there is an error at an inopportune time. Have the compound processing engine always call op_release, even when op_func sets an error in op->status. With this change, we also need nfsd4_block_get_device_info_scsi to set the gd_device pointer to NULL on error to avoid a double free.
