In the Linux kernel, the following vulnerability has been resolved: ALSA: us122l: Prevent write upgrades for read mappings The hwdep mmap callback rejects read-buffer mappings that are initially writable, but leaves VM_MAYWRITE set on mappings created with PROT_READ. A process that can open the hwdep node O_RDWR can later use mprotect() to make the mapping writable. The read allocation begins with struct usb_stream. Its read_size member is used by the fault handler to decide which pages belong to the read buffer. The read VMA intentionally remains expandable because pcm_usb_stream uses mremap() after reading that size. Changing read_size first can therefore map and access pages beyond the allocation. The same member is also consumed by usb_stream_free(), where changing it can make free_pages_exact() release pages outside the allocation. Clear VM_MAYWRITE for read-buffer mappings after rejecting an initially writable VMA. This keeps the separate output-buffer mapping writable while preventing later permission upgrades.

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1792243434 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: ethernet: hisilicon: hns:
    hns_dsaf_misc: fix a possible array overflow in hns_dsaf_ge_srst_by_port() The if statement: if (port >=     DSAF_GE_NUM) return; limits the value of port less than DSAF_GE_NUM (i.e., 8). However, if the value of     port is 6 or 7, an array overflow could occur: port_rst_off = dsaf_dev->mac_cb[port]->port_rst_off;
    because the length of dsaf_dev->mac_cb is DSAF_MAX_PORT_NUM (i.e., 6). To fix this possible array     overflow, we first check port and if it is greater than or equal to DSAF_MAX_PORT_NUM, the function     returns. (CVE-2021-47548)

  - In the Linux kernel, the following vulnerability has been resolved: dm: call the resume method on internal     suspend There is this reported crash when experimenting with the lvm2 testsuite. The list corruption is     caused by the fact that the postsuspend and resume methods were not paired correctly; there were two     consecutive calls to the origin_postsuspend function. The second call attempts to remove the hash_list     entry from a list, while it was already removed by the first call. Fix __dm_internal_resume so that it     calls the preresume and resume methods of the table's targets. If a preresume method of some target fails,     we are in a tricky situation. We can't return an error because dm_internal_resume isn't supposed to return     errors. We can't return success, because then the resume and postsuspend methods would not be paired     correctly. So, we set the DMF_SUSPENDED flag and we fake normal suspend - it may confuse userspace tools,     but it won't cause a kernel crash. ------------[ cut here ]------------ kernel BUG at lib/list_debug.c:56!     invalid opcode: 0000 [#1] PREEMPT SMP CPU: 1 PID: 8343 Comm: dmsetup Not tainted 6.8.0-rc6 #4 Hardware     name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014 RIP:

  - In the Linux kernel, the following vulnerability has been resolved: drm/client: Fully protect modes[] with     dev->mode_config.mutex The modes[] array contains pointers to modes on the connectors' mode lists, which     are protected by dev->mode_config.mutex. Thus we need to extend modes[] the same protection or by the time     we use it the elements may already be pointing to freed/reused memory. (CVE-2024-35950)

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.

  - ALSA: us122l: Prevent write upgrades for read mappings The hwdep mmap callback rejects read-buffer     mappings that are initially writable, but leaves VM_MAYWRITE set on mappings created with PROT_READ. A     process that can open the hwdep node O_RDWR can later use mprotect() to make the mapping writable. The     read allocation begins with struct usb_stream. Its read_size member is used by the fault handler to decide     which pages belong to the read buffer. The read VMA intentionally remains expandable because     pcm_usb_stream uses mremap() after reading that size. Changing read_size first can therefore map and     access pages beyond the allocation. The same member is also consumed by usb_stream_free(), where changing     it can make free_pages_exact() release pages outside the allocation. Clear VM_MAYWRITE for read-buffer     mappings after rejecting an initially writable VMA. This keeps the separate output-buffer mapping writable     while preventing later permission upgrades. (CVE-2026-97931)

Note that Nessus relies on the presence of the package as reported by the vendor.
