This\ncan lead to an unexpected \"BUG: kernel NULL pointer dereference\" if\nthe corresponding decompressor isn't built-in.\n\nFix this by checking against `sbi->available_compr_algs` for each\nm_algorithmformat request.  Incorrect !erofs_sb_has_compr_cfgs preset\nbitmap is now fixed together since it was harmless previously.\n\ud83d\udccf Published: 2024-02-22T16:13:34.315Z\n\ud83d\udccf Modified: 2025-04-22T16:19:05.199Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/47467e04816cb297905c0f09bc2d11ef865942d9\n2. https://git.kernel.org/stable/c/823ba1d2106019ddf195287ba53057aee33cf724\n3. https://git.kernel.org/stable/c/eed24b816e50c6cd18cbee0ff0d7218c8fced199\n4. https://git.kernel.org/stable/c/118a8cf504d7dfa519562d000f423ee3ca75d2c4", "creation_timestamp": "2025-04-22T17:03:38.000000Z"}, {"uuid": "a47535ca-025c-466d-9865-04e697dbac4b", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2024-26590", "type": "seen", "source": "https://t.me/ctinow/191013", "content": "https://ift.tt/5YjBWzh\nCVE-2024-26590", "creation_timestamp": "2024-02-22T18:53:45.000000Z"}]}
