In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: oss: Fix race at SNDCTL_DSP_SYNC There is a small race window at snd_pcm_oss_sync() that is called from OSS PCM SNDCTL_DSP_SYNC ioctl; namely the function calls snd_pcm_oss_make_ready() at first, then takes the params_lock mutex for the rest. When the stream is set up again by another thread between them, it leads to inconsistency, and may result in unexpected results such as NULL dereference of OSS buffer as a fuzzer spotted recently. The fix is simply to cover snd_pcm_oss_make_ready() call into the same params_lock mutex with snd_pcm_oss_make_ready_locked() variant.

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:1027-1 advisory.

    The SUSE Linux Enterprise 15 SP4 kernel was updated to receive various security bugfixes.


    The following security bugs were fixed:

    - CVE-2024-2201: Fixed information leak in x86/BHI (bsc#1217339).
    - CVE-2024-41092: drm/i915/gt: Fix potential UAF by revoke of fence registers (bsc#1228483).
    - CVE-2024-42098: crypto: ecdh - explicitly zeroize private_key (bsc#1228779).
    - CVE-2024-42229: crypto: aead,cipher - zeroize key buffer after use (bsc#1228708).
    - CVE-2024-57996: net_sched: sch_sfq: do not allow 1 packet limit (bsc#1239076).
    - CVE-2024-58014: wifi: brcmsmac: add gain range check to wlc_phy_iqcal_gainparams_nphy() (bsc#1239109).
    - CVE-2025-21718: net: rose: fix timer races against user threads (bsc#1239073).
    - CVE-2025-21780: drm/amdgpu: avoid buffer overflow attach in smu_sys_set_pp_table() (bsc#1239115).


Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
