In the Linux kernel, the following vulnerability has been resolved: ionic: fix kernel panic in XDP_TX action In the XDP_TX path, ionic driver sends a packet to the TX path with rx page and corresponding dma address. After tx is done, ionic_tx_clean() frees that page. But RX ring buffer isn't reset to NULL. So, it uses a freed page, which causes kernel panic.

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the kernel-5.14.0-516.el9 build changelog.

  - In the Linux kernel, the following vulnerability has been resolved: r8169: Fix possible ring buffer     corruption on fragmented Tx packets. An issue was found on the RTL8125b when transmitting small fragmented     packets, whereby invalid entries were inserted into the transmit ring buffer, subsequently leading to     calls to dma_unmap_single() with a null address. This was caused by rtl8169_start_xmit() not noticing     changes to nr_frags which may occur when small packets are padded (to work around hardware quirks) in     rtl8169_tso_csum_v2(). To fix this, postpone inspecting nr_frags until after any padding has been applied.
    (CVE-2024-38586)

  - In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Avoid unnecessary     destruction of file_ida file_ida is allocated during cdev open and is freed accordingly during cdev     release. This sequence is guaranteed by driver file operations. Therefore, there is no need to destroy an     already empty file_ida when the WQ cdev is removed. Worse, ida_free() in cdev release may happen after     destruction of file_ida per WQ cdev. This can lead to accessing an id in file_ida after it has been     destroyed, resulting in a kernel panic. Remove ida_destroy(&file_ida) to address these issues.

  - In the Linux kernel, the following vulnerability has been resolved: ionic: fix kernel panic in XDP_TX     action In the XDP_TX path, ionic driver sends a packet to the TX path with rx page and corresponding dma     address.

  - In the Linux kernel, the following vulnerability has been resolved: tipc: Return non-zero value from     tipc_udp_addr2str() on error tipc_udp_addr2str() should return non-zero value if the UDP media address is     invalid. Otherwise, a buffer overflow access can occur in tipc_media_addr_printf(). Fix this by returning     1 on an invalid UDP media address. (CVE-2024-42284)

  - In the Linux kernel, the following vulnerability has been resolved: dma: fix call order in     dmam_free_coherent dmam_free_coherent() frees a DMA allocation, which makes the freed vaddr available for     reuse, then calls devres_destroy() to remove and free the data structure used to track the DMA allocation.
    Between the two calls, it is possible for a concurrent task to make an allocation with the same vaddr and     add it to the devres list. If this happens, there will be two entries in the devres list with the same     vaddr and devres_destroy() can free the wrong entry, triggering the WARN_ON() in dmam_match. Fix by     destroying the devres entry before freeing the DMA allocation. kokonut //net/encryption     http://sponge2/b9145fe6-0f72-4325-ac2f-a84d81075b03 (CVE-2024-43856)

  - In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix CT entry update leaks     of modify header context The cited commit allocates a new modify header to replace the old one when     updating CT entry. But if failed to allocate a new one, eg. exceed the max number firmware can support,     modify header will be an error pointer that will trigger a panic when deallocating it. And the old modify     header point is copied to old attr. When the old attr is freed, the old modify header is lost. Fix it by     restoring the old attr to attr when failed to allocate a new modify header context. So when the CT entry     is freed, the right modify header context will be freed. And the panic of accessing error pointer is also     fixed. (CVE-2024-43864)

  - In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Always drain health in     shutdown callback There is no point in recovery during device shutdown. if health work started need to     wait for it to avoid races and NULL pointer access. Hence, drain health WQ on shutdown callback.
    (CVE-2024-43866)

  - In the Linux kernel, the following vulnerability has been resolved: memcg: protect concurrent access to     mem_cgroup_idr Commit 73f576c04b94 (mm: memcontrol: fix cgroup creation failure after many small jobs)     decoupled the memcg IDs from the CSS ID space to fix the cgroup creation failures. It introduced IDR to     maintain the memcg ID space. The IDR depends on external synchronization mechanisms for modifications. For     the mem_cgroup_idr, the idr_alloc() and idr_replace() happen within css callback and thus are protected     through cgroup_mutex from concurrent modifications. However idr_remove() for mem_cgroup_idr was not     protected against concurrency and can be run concurrently for different memcgs when they hit their refcnt     to zero. Fix that. We have been seeing list_lru based kernel crashes at a low frequency in our fleet for a     long time. These crashes were in different part of list_lru code including list_lru_add(), list_lru_del()     and reparenting code. Upon further inspection, it looked like for a given object (dentry and inode), the     super_block's list_lru didn't have list_lru_one for the memcg of that object. The initial suspicions were     either the object is not allocated through kmem_cache_alloc_lru() or somehow memcg_list_lru_alloc() failed     to allocate list_lru_one() for a memcg but returned success. No evidence were found for these cases.
    Looking more deeply, we started seeing situations where valid memcg's id is not present in mem_cgroup_idr     and in some cases multiple valid memcgs have same id and mem_cgroup_idr is pointing to one of them. So,     the most reasonable explanation is that these situations can happen due to race between multiple     idr_remove() calls or race between idr_alloc()/idr_replace() and idr_remove(). These races are causing     multiple memcgs to acquire the same ID and then offlining of one of them would cleanup list_lrus on the     system for all of them. Later access from other memcgs to the list_lru cause crashes due to missing     list_lru_one. (CVE-2024-43892)

  - In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: SHAMPO, Fix invalid WQ     linked list unlink When all the strides in a WQE have been consumed, the WQE is unlinked from the WQ     linked list (mlx5_wq_ll_pop()). For SHAMPO, it is possible to receive CQEs with 0 consumed strides for the     same WQE even after the WQE is fully consumed and unlinked. This triggers an additional unlink for the     same wqe which corrupts the linked list. Fix this scenario by accepting 0 sized consumed strides without     unlinking the WQE again. (CVE-2024-44970)

  - In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix double DMA unmapping for     XDP_REDIRECT Remove the dma_unmap_page_attrs() call in the driver's XDP_REDIRECT code path. This should     have been removed when we let the page pool handle the DMA mapping. This bug causes the warning: WARNING:

  - In the Linux kernel, the following vulnerability has been resolved: KVM: s390: fix validity interception     issue when gisa is switched off We might run into a SIE validity if gisa has been disabled either via     using kernel parameter kvm.use_gisa=0 or by setting the related sysfs attribute to N (echo N     >/sys/module/kvm/parameters/use_gisa). The validity is caused by an invalid value in the SIE control     block's gisa designation. That happens because we pass the uninitialized gisa origin to virt_to_phys()     before writing it to the gisa designation. To fix this we return 0 in kvm_s390_get_gisa_desc() if the     origin is 0. kvm_s390_get_gisa_desc() is used to determine which gisa designation to set in the SIE     control block. A value of 0 in the gisa designation disables gisa usage. The issue surfaces in the host     kernel with the following kernel message as soon a new kvm guest start is attemted. kvm: unhandled     validity intercept 0x1011 WARNING: CPU: 0 PID: 781237 at arch/s390/kvm/intercept.c:101     kvm_handle_sie_intercept+0x42e/0x4d0 [kvm] Modules linked in: vhost_net tap tun xt_CHECKSUM xt_MASQUERADE     xt_conntrack ipt_REJECT xt_tcpudp nft_compat x_tables nf_nat_tftp nf_conntrack_tftp vfio_pci_core     irqbypass vhost_vsock vmw_vsock_virtio_transport_common vsock vhost vhost_iotlb kvm nft_fib_inet     nft_fib_ipv4 nft_fib_ipv6 nft_fib nft_reject_inet nf_reject_ipv4 nf_reject_ipv6 nft_reject nft_ct     nft_chain_nat nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 ip_set nf_tables sunrpc mlx5_ib ib_uverbs     ib_core mlx5_core uvdevice s390_trng eadm_sch vfio_ccw zcrypt_cex4 mdev vfio_iommu_type1 vfio sch_fq_codel     drm i2c_core loop drm_panel_orientation_quirks configfs nfnetlink lcs ctcm fsm dm_service_time ghash_s390     prng chacha_s390 libchacha aes_s390 des_s390 libdes sha3_512_s390 sha3_256_s390 sha512_s390 sha256_s390     sha1_s390 sha_common dm_mirror dm_region_hash dm_log zfcp scsi_transport_fc scsi_dh_rdac scsi_dh_emc     scsi_dh_alua pkey zcrypt dm_multipath rng_core autofs4 [last unloaded: vfio_pci] CPU: 0 PID: 781237 Comm:
