CVE-2022-50057

CVE-2022-50057 affects the Linux kernel ntfs3 file system. The vulnerability is a NULL dereference in ntfs_update_mftmirr where, if ntfs_fill_super() wasn’t called, sbi->sb could be NULL and dereferenced. The failure path is triggered by certain mount parameters (e.g., an invalid or unexpected...

CVE-2022-50049 ASoC: DPCM: Don't pick up BE without substream

In the Linux kernel, the following vulnerability has been resolved: ASoC: DPCM: Don't pick up BE without substream When DPCM tries to add valid BE connections at dpcmaddpaths, it doesn't check whether the picked BE actually supports for the given stream direction. Due to that, when an asymmetric ...

CVE-2022-50001

The CVE-2022-50001 issue affects the Linux kernel netfilter component nft_tproxy. The root cause was that TPROXY could be used from non-prerouting paths, leading to a null dereference crash. The fix restricts nft_tproxy to the prerouting hook, requiring a check that it runs only in prerouting. Th...

CVE-2022-50001 netfilter: nft_tproxy: restrict to prerouting hook

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfttproxy: restrict to prerouting hook TPROXY is only allowed from prerouting, but nfttproxy doesn't check this. This fixes a crash null dereference when using tproxy from e.g. output...
