In the Linux kernel, the following vulnerability has been resolved: bpf: Fix memory leaks in __check_func_call kmemleak reports this issue: unreferenced object 0xffff88817139d000 (size 2048): comm "test_progs", pid 33246, jiffies 4307381979 (age 45851.820s) hex dump (first 32 bytes): 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace: [<0000000045f075f0>] kmalloc_trace+0x27/0xa0 [<0000000098b7c90a>] __check_func_call+0x316/0x1230 [<00000000b4c3c403>] check_helper_call+0x172e/0x4700 [<00000000aa3875b7>] do_check+0x21d8/0x45e0 [<000000001147357b>] do_check_common+0x767/0xaf0 [<00000000b5a595b4>] bpf_check+0x43e3/0x5bc0 [<0000000011e391b1>] bpf_prog_load+0xf26/0x1940 [<0000000007f765c0>] __sys_bpf+0xd2c/0x3650 [<00000000839815d6>] __x64_sys_bpf+0x75/0xc0 [<00000000946ee250>] do_syscall_64+0x3b/0x90 [<0000000000506b7f>] entry_SYSCALL_64_after_hwframe+0x63/0xcd The root case here is: In function prepare_func_exit(), the callee is not released in the abnormal scenario after "state->curframe--;". To fix, move "state->curframe--;" to the very bottom of the function, right when we free callee and reset frame[] pointer to NULL, as Andrii suggested. In addition, function __check_func_call() has a similar problem. In the abnormal scenario before "state->curframe++;", the callee also should be released by free_func_state().

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of kernel installed on the remote host is prior to 5.15.86-53.137. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2023-012 advisory.

    A flaw was found in the Linux kernel. A denial of service flaw may occur if there is a consecutive request     of the NVME_IOCTL_RESET and the NVME_IOCTL_SUBSYS_RESET through the device file of the driver, resulting     in a PCIe link disconnect. (CVE-2022-3169)

    A vulnerability classified as critical has been found in Linux Kernel. Affected is the function     btf_dump_name_dups of the file tools/lib/bpf/btf_dump.c of the component libbpf. The manipulation leads to     use after free. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability     is VDB-211032. (CVE-2022-3534)

    Guests can trigger NIC interface reset/abort/crash via netback It is possible for a guest to trigger a NIC     interface reset/abort/crash in a Linux based network backend by sending certain kinds of packets. It     appears to be an (unwritten?) assumption in the rest of the Linux network stack that packet protocol     headers are all contained within the linear section of the SKB and some NICs behave badly if this is not     the case. This has been reported to occur with Cisco (enic) and Broadcom NetXtrem II BCM5780 (bnx2x)     though it may be an issue with other NICs/drivers as well. In case the frontend is sending requests with     split headers, netback will forward those violating above mentioned assumption to the networking core,     resulting in said misbehavior. (CVE-2022-3643)

    An incorrect TLB flush issue was found in the Linux kernel's GPU i915 kernel driver, potentially leading     to random memory corruption or data leaks. This flaw could allow a local user to crash the system or     escalate their privileges on the system. (CVE-2022-4139)

    Guests can trigger deadlock in Linux netback driver T[his CNA information record relates to multiple CVEs;
    the text explains which aspects/vulnerabilities correspond to which CVE.] The patch for XSA-392 introduced     another issue which might result in a deadlock when trying to free the SKB of a packet dropped due to the     XSA-392 handling (CVE-2022-42328). Additionally when dropping packages for other reasons the same deadlock     could occur in case of netpoll being active for the interface the xen-netback driver is connected to     (CVE-2022-42329). (CVE-2022-42328)

(CVE-2022-42329)

    A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain     kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their     privileges on the system. (CVE-2022-4378)

    A use-after-free vulnerability was found in __nfs42_ssc_open() in fs/nfs/nfs4file.c in the Linux kernel.
    This flaw allows an attacker to conduct a remote denial of service. (CVE-2022-4379)

    A race condition in the x86 KVM subsystem in the Linux kernel through 6.1-rc6 allows guest OS users to     cause a denial of service (host OS crash or host OS memory corruption) when nested virtualisation and the     TDP MMU are enabled. (CVE-2022-45869)
