The version of kernel installed on the remote host is prior to 5.4.269-183.369. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2024-062 advisory.

  - dm_table_create in drivers/md/dm-table.c in the Linux kernel through 6.7.4 can attempt to (in     alloc_targets) allocate more than INT_MAX bytes, and crash, because of a missing check for struct     dm_ioctl.target_count. (CVE-2023-52429)

  - In the Linux kernel, the following vulnerability has been resolved: net: prevent mss overflow in     skb_segment() Once again syzbot is able to crash the kernel in skb_segment() [1] GSO_BY_FRAGS is a     forbidden value, but unfortunately the following computation in skb_segment() can reach it quite easily :
    mss = mss * partial_segs; 65535 = 3 * 5 * 17 * 257, so many initial values of mss can lead to a bad final     result. Make sure to limit segmentation so that the new mss value is smaller than GSO_BY_FRAGS. [1]     general protection fault, probably for non-canonical address 0xdffffc000000000e: 0000 [#1] PREEMPT SMP     KASAN KASAN: null-ptr-deref in range [0x0000000000000070-0x0000000000000077] CPU: 1 PID: 5079 Comm: syz-     executor993 Not tainted 6.7.0-rc4-syzkaller-00141-g1ae4cd3cbdd0 #0 Hardware name: Google Google Compute     Engine/Google Compute Engine, BIOS Google 11/10/2023 RIP: 0010:skb_segment+0x181d/0x3f30     net/core/skbuff.c:4551 Code: 83 e3 02 e9 fb ed ff ff e8 90 68 1c f9 48 8b 84 24 f8 00 00 00 48 8d 78 70 48     b8 00 00 00 00 00 fc ff df 48 89 fa 48 c1 ea 03 <0f> b6 04 02 84 c0 74 08 3c 03 0f 8e 8a 21 00 00 48 8b 84     24 f8 00 RSP: 0018:ffffc900043473d0 EFLAGS: 00010202 RAX: dffffc0000000000 RBX: 0000000000010046 RCX:

  - A flaw was found in the ATA over Ethernet (AoE) driver in the Linux kernel. The aoecmd_cfg_pkts() function     improperly updates the refcnt on `struct net_device`, and a use-after-free can be triggered by racing     between the free on the struct and the access through the `skbtxq` global queue. This could lead to a     denial of service condition or potential code execution. (CVE-2023-6270)

  - A vulnerability was found in vhost_new_msg in drivers/vhost/vhost.c in the Linux kernel, which does not     properly initialize memory in messages passed between virtual guests and the host operating system in the     vhost/vhost.c:vhost_new_msg() function. This issue can allow local privileged users to read some kernel     memory contents when reading from the /dev/vhost-net device file. (CVE-2024-0340)

  - A vulnerability was reported in the Open vSwitch sub-component in the Linux Kernel. The flaw occurs when a     recursive operation of code push recursively calls into the code block. The OVS module does not validate     the stack depth, pushing too many frames and causing a stack overflow. As a result, this can lead to a     crash or other related issues. (CVE-2024-1151)

  - A Speculative Race Condition (SRC) vulnerability that impacts modern CPU architectures supporting     speculative execution (related to Spectre V1) has been disclosed. An unauthenticated attacker can exploit     this vulnerability to disclose arbitrary data from the CPU using race conditions to access the speculative     executable code paths. (CVE-2024-2193)

  - In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_set_rbtree: skip end     interval element from gc rbtree lazy gc on insert might collect an end interval element that has been just     added in this transactions, skip end interval elements that are not yet active. (CVE-2024-26581)

  - In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic-its: Avoid potential     UAF in LPI translation cache There is a potential UAF scenario in the case of an LPI translation cache hit     racing with an operation that invalidates the cache, such as a DISCARD ITS command. The root of the     problem is that vgic_its_check_cache() does not elevate the refcount on the vgic_irq before dropping the     lock that serializes refcount changes. Have vgic_its_check_cache() raise the refcount on the returned     vgic_irq and add the corresponding decrement after queueing the interrupt. (CVE-2024-26598)

  - In the Linux kernel, the following vulnerability has been resolved: sched/membarrier: reduce the ability     to hammer on sys_membarrier On some systems, sys_membarrier can be very expensive, causing overall     slowdowns for everything. So put a lock on the path in order to serialize the accesses to prevent the     ability for this to be called at too high of a frequency and saturate the machine. (CVE-2024-26602)
