In the Linux kernel, the following vulnerability has been resolved: RDMA/srpt: Fix srpt_alloc_rw_ctxs() unwind counters When srpt_alloc_rw_ctxs() fails partway through a multi-buffer indirect descriptor, the unwind path destroys RDMA contexts but leaves stale n_rw_ctx and n_rdma values (and a dangling rw_ctxs pointer). Later sq_wr_avail accounting in srpt_queue_response() or srpt_write_pending() can then subtract the wrong number of send queue credits. Reset the counters and clear rw_ctxs after freeing the heap allocation before returning an error.

Going to next bucket may not only skip the elements in current bucket     silently, but also incur out-of-bound memory access or expose kernel memory to userspace if current     bucket_cnt is greater than bucket_size or zero.

One instance where it can happen is when userspace sends an IOTLB message with     iova=size=uaddr=0 (vhost_process_iotlb_msg). So, an entry with size = 0, start = 0, last = ULONG_MAX ends     up in the iotlb. Next time a packet is sent, iotlb_access_ok() loops indefinitely due to that erroneous     entry.

  - In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd: Fix crash due to race     between amd_pmu_enable_all, perf NMI and throttling amd_pmu_enable_all() does: if (!test_bit(idx,     cpuc->active_mask)) continue; amd_pmu_enable_event(cpuc->events[idx]); A perf NMI of another event can     come between these two steps. Perf NMI handler internally disables and enables _all_ events, including the     one which nmi-intercepted amd_pmu_enable_all() was in process of enabling. If that unintentionally enabled     event has very low sampling period and causes immediate successive NMI, causing the event to be throttled,     cpuc->events[idx] and cpuc->active_mask gets cleared by x86_pmu_stop(). This will result in     amd_pmu_enable_event() getting called with event=NULL when amd_pmu_enable_all() resumes after handling the     NMIs. This causes a kernel crash: BUG: kernel NULL pointer dereference, address: 0000000000000198 #PF:

This will solve the issue by not enabling those events whose     active_masks are set but are not yet enabled in hw pmu. (CVE-2022-49781)

  - In the Linux kernel, the following vulnerability has been resolved: blk-iolatency: Fix memory leak on     add_disk() failures When a gendisk is successfully initialized but add_disk() fails such as when a loop     device has invalid number of minor device numbers specified, blkcg_init_disk() is called during init and     then blkcg_exit_disk() during error handling. Unfortunately, iolatency gets initialized in the former but     doesn't get cleaned up in the latter. This is because, in non-error cases, the cleanup is performed by     del_gendisk() calling rq_qos_exit(), the assumption being that rq_qos policies, iolatency being one of     them, can only be activated once the disk is fully registered and visible. That assumption is true for wbt     and iocost, but not so for iolatency as it gets initialized before add_disk() is called. It is desirable     to lazy-init rq_qos policies because they are optional features and add to hot path overhead once     initialized - each IO has to walk all the registered rq_qos policies. So, we want to switch iolatency to     lazy init too. However, that's a bigger change. As a fix for the immediate problem, let's just add an     extra call to rq_qos_exit() in blkcg_exit_disk(). This is safe because duplicate calls to rq_qos_exit()     become noop's. (CVE-2022-50550)

  - In the Linux kernel, the following vulnerability has been resolved: usb: roles: fix NULL pointer issue     when put module's reference In current design, usb role class driver will get usb_role_switch parent's     module reference after the user get usb_role_switch device and put the reference after the user put the     usb_role_switch device. However, the parent device of usb_role_switch may be removed before the user put     the usb_role_switch. If so, then, NULL pointer issue will be met when the user put the parent module's     reference. This will save the module pointer in structure of usb_role_switch. Then, we don't need to find     module by iterating long relations. (CVE-2024-26747)

The CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS-STREAM8:CLSA-2026:1791780738 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: mm/khugepaged: invoke MMU notifiers in     shmem/file collapse paths Any codepath that zaps page table entries must invoke MMU notifiers to ensure     that secondary MMUs (like KVM) don't keep accessing pages which aren't mapped anymore. Secondary MMUs     don't hold their own references to pages that are mirrored over, so failing to notify them can lead to     page use-after-free. I'm marking this as addressing an issue introduced in commit f3f0e1d2150b     (khugepaged: add support of collapse for tmpfs/shmem pages), but most of the security impact of this     only came in commit 27e1f8273113 (khugepaged: enable collapse pmd for pte-mapped THP), which actually     omitted flushes for the removal of present PTEs, not just for the removal of empty page tables.

  - In the Linux kernel, the following vulnerability has been resolved: virtio_net: fix xdp_rxq_info bug after     suspend/resume The following sequence currently causes a driver bug warning when using virtio_net: # ip     link set eth0 up # echo mem > /sys/power/state (or e.g. # rtcwake -s 10 -m mem) <resume> # ip link set     eth0 down Missing register, driver bug WARNING: CPU: 0 PID: 375 at net/core/xdp.c:138     xdp_rxq_info_unreg+0x58/0x60 Call trace: xdp_rxq_info_unreg+0x58/0x60 virtnet_close+0x58/0xac

This happens because virtnet_freeze() frees the receive_queue completely     (including struct xdp_rxq_info) but does not call xdp_rxq_info_unreg(). Similarly, virtnet_restore() sets     up the receive_queue again but does not call xdp_rxq_info_reg(). Actually, parts of virtnet_freeze_down()     and virtnet_restore_up() are almost identical to virtnet_close() and virtnet_open(): only the calls to     xdp_rxq_info_(un)reg() are missing. This means that we can fix this easily and avoid such problems in the     future by just calling virtnet_close()/open() from the freeze/restore handlers. Aside from adding the     missing xdp_rxq_info calls the only difference is that the refill work is only cancelled if     netif_running(). However, this should not make any functional difference since the refill work should only     be active if the network interface is actually up. (CVE-2022-49687)

  - In the Linux kernel, the following vulnerability has been resolved: crypto: scomp - fix req->dst buffer     overflow The req->dst buffer size should be checked before copying from the scomp_scratch->dst to avoid     req->dst buffer overflow problem. (CVE-2023-52612)

  - In the Linux kernel, the following vulnerability has been resolved: net: atlantic: eliminate double free     in error handling logic Driver has a logic leak in ring data allocation/free, where aq_ring_free could be     called multiple times on same ring, if system is under stress and got memory allocation error. Ring     pointer was used as an indicator of failure, but this is not correct since only ring data is     allocated/deallocated. Ring itself is an array member. Changing ring allocation functions to return error     code directly. This simplifies error handling and eliminates aq_ring_free on higher layer.
    (CVE-2023-52664)

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.

  - RDMA/srpt: Fix srpt_alloc_rw_ctxs() unwind counters When srpt_alloc_rw_ctxs() fails partway through a     multi-buffer indirect descriptor, the unwind path destroys RDMA contexts but leaves stale n_rw_ctx and     n_rdma values (and a dangling rw_ctxs pointer). Later sq_wr_avail accounting in srpt_queue_response() or     srpt_write_pending() can then subtract the wrong number of send queue credits. Reset the counters and     clear rw_ctxs after freeing the heap allocation before returning an error. (CVE-2026-100075)

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