{"id":"CVE-2026-53291","summary":"ALSA: hda/conexant: Fix missing error check for jack detection","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: hda/conexant: Fix missing error check for jack detection\n\nIn cx_probe(), the return value of snd_hda_jack_detect_enable_callback()\nis ignored. This function returns a pointer, and if it fails (e.g., due\nto memory allocation failure), it returns an error pointer which must\nbe checked using IS_ERR().\n\nIf the registration fails, the driver continues to probe, but the jack\ndetection callback will not be registered. This can lead to a kernel\ncrash later when the driver attempts to handle jack events or accesses\nthe uninitialized structure.\n\nCheck the return value using IS_ERR() and propagate the error via\nPTR_ERR() to the probe caller.","modified":"2026-10-08T02:51:25.826521329Z","published":"2026-06-26T19:40:50.808Z","related":["SUSE-SU-2026:23193-1","SUSE-SU-2026:23194-1","SUSE-SU-2026:23241-1","SUSE-SU-2026:23244-1","SUSE-SU-2026:23881-1","SUSE-SU-2026:23887-1","SUSE-SU-2026:23897-1","SUSE-SU-2026:23902-1","SUSE-SU-2026:3790-1","SUSE-SU-2026:3810-1","openSUSE-SU-2026:21910-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53291.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1da5c73f3793b224696617a2a21def7500ba18d6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/49c2c5924552e1d2f8b635dee663abebbb7cf63b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a2a33e87a2ffce3046c574d24eec4390c27c9365"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b0e2333a231107adedd38c6fcfe1adc6162716fc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d68f753d89f4ef6e410d7e8b7e8ab2fdde921b80"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dd110cc00cf854a8ecd8d003127a4178c28574ea"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f837c7b85143a7c54140ff41ad5c076b73cd9933"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53291.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53291"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"f13b8cb5a6920ad98b751d3134686f29810577d4"},{"fixed":"49c2c5924552e1d2f8b635dee663abebbb7cf63b"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"2cb659ef0ac744545499e7c37665b276d9e405da"},{"fixed":"a2a33e87a2ffce3046c574d24eec4390c27c9365"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"24d748413cc4e1d97074bae1f335d32d30912f10"},{"fixed":"d68f753d89f4ef6e410d7e8b7e8ab2fdde921b80"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"7aeb259086487417f0fecf66e325bee133e8813a"},{"fixed":"dd110cc00cf854a8ecd8d003127a4178c28574ea"},{"fixed":"f837c7b85143a7c54140ff41ad5c076b73cd9933"},{"fixed":"1da5c73f3793b224696617a2a21def7500ba18d6"},{"fixed":"b0e2333a231107adedd38c6fcfe1adc6162716fc"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5.15.149"},{"fixed":"5.15.209"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.1.77"},{"fixed":"6.1.175"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.6.16"},{"fixed":"6.6.141"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.7.4"},{"fixed":"6.8"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4a28302b2c681e3cf85e3b41231fff363c4c6a0e"}]}],"versions":["v5.15.208","v5.15.207","v5.15.206","v5.15.205","v5.15.204","v5.15.203","v5.15.202","v5.15.201","v5.15.200","v5.15.199","v5.15.198","v5.15.197","v5.15.196","v5.15.195","v5.15.194","v5.15.193","v5.15.192","v5.15.191","v5.15.190","v5.15.189","v5.15.188","v5.15.187","v5.15.186","v5.15.185","v5.15.184","v5.15.183","v5.15.182","v5.15.181","v5.15.180","v5.15.179","v5.15.178","v5.15.177","v5.15.176","v5.15.175","v5.15.174","v5.15.173","v5.15.172","v5.15.171","v5.15.170","v5.15.169","v5.15.168","v5.15.167","v5.15.166","v5.15.165","v5.15.164","v5.15.163","v5.15.162","v5.15.161","v5.15.160","v5.15.159","v5.15.158","v5.15.157","v5.15.156","v5.15.155","v5.15.154","v5.15.153","v5.15.152","v5.15.151","v5.15.150","v5.15.149","v6.1.174","v6.1.173","v6.1.172","v6.1.171","v6.1.170","v6.1.169","v6.1.168","v6.1.167","v6.1.166","v6.1.165","v6.1.164","v6.1.163","v6.1.162","v6.1.161","v6.1.160","v6.1.159","v6.1.158","v6.1.157","v6.1.156","v6.1.155","v6.1.154","v6.1.153","v6.1.152","v6.1.151","v6.1.150","v6.1.149","v6.1.148","v6.1.147","v6.1.146","v6.1.145","v6.1.144","v6.1.143","v6.1.142","v6.1.141","v6.1.140","v6.1.139","v6.1.138","v6.1.137","v6.1.136","v6.1.135","v6.1.134","v6.1.133","v6.1.132","v6.1.131","v6.1.130","v6.1.129","v6.1.128","v6.1.127","v6.1.126","v6.1.125","v6.1.124","v6.1.123","v6.1.122","v6.1.121","v6.1.120","v6.1.119","v6.1.118","v6.1.117","v6.1.116","v6.1.115","v6.1.114","v6.1.113","v6.1.112","v6.1.111","v6.1.110","v6.1.109","v6.1.108","v6.1.107","v6.1.106","v6.1.105","v6.1.104","v6.1.103","v6.1.102","v6.1.101","v6.1.100","v6.1.99","v6.1.98","v6.1.97","v6.1.96","v6.1.95","v6.1.94","v6.1.93","v6.1.92","v6.1.91","v6.1.90","v6.1.89","v6.1.88","v6.1.87","v6.1.86","v6.1.85","v6.1.84","v6.1.83","v6.1.82","v6.1.81","v6.1.80","v
