In the Linux kernel, the following vulnerability has been resolved: HID: roccat: free buffered reports when destroying device roccat_report_event() duplicates each report with kmemdup() and stores the allocation in a circular-buffer slot. The allocation is released only when that slot is reused. The device destruction paths free struct roccat_device without releasing reports still stored in cbuf[]. This makes those allocations unreachable and leaks up to ROCCAT_CBUF_SIZE report buffers per device. Add a small destructor that frees every buffered report before freeing the device, and use it in both paths that can destroy a registered device.

The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2026:1792751247 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: mmmremap.c: avoid pointless     invalidate_range_start/end on mremap(old_size=0) If an mremap() syscall with old_size=0 ends up in     move_page_tables(), it will call invalidate_range_start()/invalidate_range_end() unnecessarily, i.e. with     an empty range. This causes a WARN in KVM's mmu_notifier. In the past, empty ranges have been diagnosed to     be off-by-one bugs, hence the WARNing. Given the low (so far) number of unique reports, the benefits of     detecting more buggy callers seem to outweigh the cost of having to fix cases such as this one, where     userspace is doing something silly. In this particular case, an early return from move_page_tables() is     enough to fix the issue. (CVE-2022-49077)

  - In the Linux kernel, the following vulnerability has been resolved: virtio_console: eliminate anonymous     module_init & module_exit Eliminate anonymous module_init() and module_exit(), which can lead to confusion     or ambiguity when reading System.map, crashes/oops/bugs, or an initcall_debug log. Give each of these init     and exit functions unique driver-specific names to eliminate the anonymous names. Example 1: (System.map)     ffffffff832fc78c t init ffffffff832fc79e t init ffffffff832fc8f8 t init Example 2: (initcall_debug log)     calling init+0x0/0x12 @ 1 initcall init+0x0/0x12 returned 0 after 15 usecs calling init+0x0/0x60 @ 1     initcall init+0x0/0x60 returned 0 after 2 usecs calling init+0x0/0x9a @ 1 initcall init+0x0/0x9a returned     0 after 74 usecs (CVE-2022-49100)

  - In the Linux kernel, the following vulnerability has been resolved: mtd: Fix device name leak when     register device failed in add_mtd_device() There is a kmemleak when register device failed: unreferenced     object 0xffff888101aab550 (size 8): comm insmod, pid 3922, jiffies 4295277753 (age 925.408s) hex dump     (first 8 bytes): 6d 74 64 30 00 88 ff ff mtd0.... backtrace: [<00000000bde26724>]

(CVE-2022-50566)

  - In the Linux kernel, the following vulnerability has been resolved: media: dvb-frontends: fix leak of     memory fw (CVE-2022-50664)

  - In the Linux kernel, the following vulnerability has been resolved: acct: fix potential integer overflow     in encode_comp_t() The integer overflow is descripted with following codes: > 317 static comp_t     encode_comp_t(u64 value) > 318 { > 319 int exp, rnd; ...... > 341 exp <<= MANTSIZE; > 342 exp += value; >     343 return exp; > 344 } Currently comp_t is defined as type of '__u16', but the variable 'exp' is type of     'int', so overflow would happen when variable 'exp' in line 343 is greater than 65535. (CVE-2022-50749)

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.

  - HID: roccat: free buffered reports when destroying device roccat_report_event() duplicates each report     with kmemdup() and stores the allocation in a circular-buffer slot. The allocation is released only when     that slot is reused. The device destruction paths free struct roccat_device without releasing reports     still stored in cbuf[]. This makes those allocations unreachable and leaks up to ROCCAT_CBUF_SIZE report     buffers per device. Add a small destructor that frees every buffered report before freeing the device, and     use it in both paths that can destroy a registered device. (CVE-2026-89627)

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