Affected files ============== The file(s) affected by this issue are: fs/jfs/jfs_txnmgr.c 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/a88efca805bea93cea9187dfd00835aa7093bf1b https://git.kernel.org/stable/c/97c1f26e4d4af55e8584e4646dd5c5fa7baf62c7 https://git.kernel.org/stable/c/2a8807f9f511c64de0c7cc9900a1683e3d72a3e5 https://git.kernel.org/stable/c/5c094ca994824e038b6a97835ded4e5d1d808504 https://git.kernel.org/stable/c/2febd5f81e4bfba61d9f374dcca628aff374cc56 https://git.kernel.org/stable/c/aa7cdf487ab3fa47284daaccc3d7d5de01c6a84c https://git.kernel.org/stable/c/b0ed8ed0428ee96092da6fefa5cfacbe4abed701 https://git.kernel.org/stable/c/95e2b352c03b0a86c5717ba1d24ea20969abcacc
