- Summary
- CVE-2024-27020 affecting package kernel for versions less than 5.15.158.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: Fix potential data-race in _nftexprtypeget()
nftunregisterexpr() can concurrent with __nftexprtype_get(), and there is not any protection when iterate over nftablesexpressions list in _nftexprtypeget(). Therefore, there is potential data-race of nftablesexpressions list entry.
Use listforeachentryrcu() to iterate over nftablesexpressions list in __nftexprtypeget(), and use rcureadlock() in the caller nftexprtypeget() to protect the entire type query process.
