Description =========== In the Linux kernel, the following vulnerability has been resolved: tcp/dccp: Fix a data-race around sysctl_tcp_fwmark_accept. While reading sysctl_tcp_fwmark_accept, it can be changed concurrently. Thus, we need to add READ_ONCE() to its reader. The Linux kernel CVE team has assigned CVE-2022-49601 to this issue. Affected and fixed versions =========================== Issue introduced in 3.16 with commit 84f39b08d7868ce10eeaf640627cb89777f0ae93 and fixed in 4.9.325 with commit 13207f9485b5de68decf296ceb0046f5eabb2485 Issue introduced in 3.16 with commit 84f39b08d7868ce10eeaf640627cb89777f0ae93 and fixed in 4.14.290 with commit 45fc82706a97242539d6b841ddd7a077ec20757b Issue introduced in 3.16 with commit 84f39b08d7868ce10eeaf640627cb89777f0ae93 and fixed in 4.19.254 with commit abf70de2ec026ae8d7da4e79bec61888a880e00b Issue introduced in 3.16 with commit 84f39b08d7868ce10eeaf640627cb89777f0ae93 and fixed in 5.4.208 with commit a7386602a2fe2f6192477e8ede291a815da09d81 Issue introduced in 3.16 with commit 84f39b08d7868ce10eeaf640627cb89777f0ae93 and fixed in 5.10.134 with commit d4f65615db7fca3df9f7e79eadf937e6ddb03c54 Issue introduced in 3.16 with commit 84f39b08d7868ce10eeaf640627cb89777f0ae93 and fixed in 5.15.58 with commit bf3134feffe61b7a0e21f60a04743f8da0958b53 Issue introduced in 3.16 with commit 84f39b08d7868ce10eeaf640627cb89777f0ae93 and fixed in 5.18.15 with commit 526d8cf8824f613c72dba2155542295e70135f62 Issue introduced in 3.16 with commit 84f39b08d7868ce10eeaf640627cb89777f0ae93 and fixed in 5.19 with commit 1a0008f9df59451d0a17806c1ee1a19857032fa8 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2022-49601 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: include/net/inet_sock.h Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/13207f9485b5de68decf296ceb0046f5eabb2485 https://git.kernel.org/stable/c/45fc82706a97242539d6b841ddd7a077ec20757b https://git.kernel.org/stable/c/abf70de2ec026ae8d7da4e79bec61888a880e00b https://git.kernel.org/stable/c/a7386602a2fe2f6192477e8ede291a815da09d81 https://git.kernel.org/stable/c/d4f65615db7fca3df9f7e79eadf937e6ddb03c54 https://git.kernel.org/stable/c/bf3134feffe61b7a0e21f60a04743f8da0958b53 https://git.kernel.org/stable/c/526d8cf8824f613c72dba2155542295e70135f62 https://git.kernel.org/stable/c/1a0008f9df59451d0a17806c1ee1a19857032fa8
