Message-ID: <2025120936-CVE-2022-50646-37e0@gregkh> Date: Tue, 9 Dec 2025 09:01:47 +0900 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-cve-announce@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...nel.org> Subject: CVE-2022-50646: scsi: hpsa: Fix possible memory leak in hpsa_init_one() From: Greg Kroah-Hartman <gregkh@...nel.org> Description =========== In the Linux kernel, the following vulnerability has been resolved: scsi: hpsa: Fix possible memory leak in hpsa_init_one() The hpda_alloc_ctlr_info() allocates h and its field reply_map. However, in hpsa_init_one(), if alloc_percpu() failed, the hpsa_init_one() jumps to clean1 directly, which frees h and leaks the h->reply_map. Fix by calling hpda_free_ctlr_info() to release h->replay_map and h instead free h directly. The Linux kernel CVE team has assigned CVE-2022-50646 to this issue. Affected and fixed versions =========================== Issue introduced in 4.16 with commit 8b834bff1b73dce46f4e9f5e84af6f73fed8b0ef and fixed in 4.19.270 with commit f4d1c14e8b404766ff2bb8644bb19443d73965de Issue introduced in 4.16 with commit 8b834bff1b73dce46f4e9f5e84af6f73fed8b0ef and fixed in 5.4.229 with commit f8fc2f18652917cdcc89cb23f3a1b7cb6e119c5e Issue introduced in 4.16 with commit 8b834bff1b73dce46f4e9f5e84af6f73fed8b0ef and fixed in 5.10.163 with commit c808edbf580bfc454671cbe66e9d7c2e938e7601 Issue introduced in 4.16 with commit 8b834bff1b73dce46f4e9f5e84af6f73fed8b0ef and fixed in 5.15.86 with commit bfe10a1d9fbccdf39f8449d62509f070d8aaaac1 Issue introduced in 4.16 with commit 8b834bff1b73dce46f4e9f5e84af6f73fed8b0ef and fixed in 6.0.16 with commit fc998d0a7d65672f0812f11cd0ec4bbe4f8f8507 Issue introduced in 4.16 with commit 8b834bff1b73dce46f4e9f5e84af6f73fed8b0ef and fixed in 6.1.2 with commit 0aa7be66168b1e84b2581ffff3ccb54a6c804a1e Issue introduced in 4.16 with commit 8b834bff1b73dce46f4e9f5e84af6f73fed8b0ef and fixed in 6.2 with commit 9c9ff300e0de07475796495d86f449340d454a0c Issue introduced in 4.14.63 with commit 1edd825c11f8ed2c409d6fb6b3d90a042cbf738d 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-2022-50646 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: drivers/scsi/hpsa.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/f4d1c14e8b404766ff2bb8644bb19443d73965de https://git.kernel.org/stable/c/f8fc2f18652917cdcc89cb23f3a1b7cb6e119c5e https://git.kernel.org/stable/c/c808edbf580bfc454671cbe66e9d7c2e938e7601 https://git.kernel.org/stable/c/bfe10a1d9fbccdf39f8449d62509f070d8aaaac1 https://git.kernel.org/stable/c/fc998d0a7d65672f0812f11cd0ec4bbe4f8f8507 https://git.kernel.org/stable/c/0aa7be66168b1e84b2581ffff3ccb54a6c804a1e https://git.kernel.org/stable/c/9c9ff300e0de07475796495d86f449340d454a0c
