Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - f2fs: fix null-ptr-deref in f2fs_get_dnode_of_data There is issue as follows when test f2fs atomic write:
 F2FS-fs (loop0): Can't find valid F2FS filesystem in 2th superblock F2FS-fs (loop0): invalid crc_offset: 0 F2FS-fs (loop0): f2fs_check_nid_range: out-of-range nid=1, run fsck to fix. F2FS-fs (loop0):
 f2fs_check_nid_range: out-of-range nid=2, run fsck to fix.

When f2fs_do_write_data_page write cow_inode will use cow_inode's cow_inode which is NULL. Then will trigger null-ptr-deref. To solve above issue, introduce FI_COW_FILE flag for COW inode. Fiexes: 3db1de0e582c(f2fs: change the current atomic write way) (CVE-2022-50009)

Note that Nessus relies on the presence of the package as reported by the vendor.
