The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:3392-1 advisory.

  - Information exposure through microarchitectural state after transient execution in certain vector     execution units for some Intel(R) Processors may allow an authenticated user to potentially enable     information disclosure via local access. (CVE-2022-40982)

  - Copy_from_user on 64-bit versions of the Linux kernel does not implement the __uaccess_begin_nospec     allowing a user to bypass the access_ok check and pass a kernel pointer to copy_from_user(). This would     allow an attacker to leak information. We recommend upgrading beyond commit     74e19ef0ff8061ef55957c3abd71614ef0f42f47 (CVE-2023-0459)

  - A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address     prediction. This may result in speculative execution at an attacker-controlled?address, potentially     leading to information disclosure. (CVE-2023-20569)

  - An issue in Zen 2 CPUs, under specific microarchitectural circumstances, may allow an attacker to     potentially access sensitive information. (CVE-2023-20593)

  - A use after free flaw was found in hfsplus_put_super in fs/hfsplus/super.c in the Linux Kernel. This flaw     could allow a local user to cause a denial of service problem. (CVE-2023-2985)

  - A flaw in the Linux Kernel found in the GFS2 file system. On corrupted gfs2 file systems the evict code     can try to reference the journal descriptor structure, jdesc, after it has been freed and set to NULL. It     can lead to null pointer dereference when gfs2_trans_begin being called and then fail     ingfs2_evict_inode(). (CVE-2023-3212) (CVE-2023-34319)

  - Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register     contents when CAP_NET_ADMIN is in any user or network namespace (CVE-2023-35001)

  - A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux     Kernel. This flaw allows an attacker with local user access to cause a system crash or leak internal     kernel information. (CVE-2023-3567)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return     an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 04c55383fa5689357bcdd2c8036725a55ed632bc.
    (CVE-2023-3609)

  - An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited     to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-     of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend     upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64. (CVE-2023-3611)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an     error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f.
    (CVE-2023-3776)

  - A use-after-free vulnerability was found in the cxgb4 driver in the Linux kernel. The bug occurs when the     cxgb4 device is detaching due to a possible rearming of the flower_stats_timer from the work queue. This     flaw allows a local user to crash the system, causing a denial of service condition. (CVE-2023-4133)

  - A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to     bypass network filters and gain unauthorized access to some resources. The original patches fixing     CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits -     a096ccca6e50 (tun: tun_chr_open(): correctly initialize socket uid), - 66b2c338adce (tap: tap_open():
    correctly initialize socket uid), pass inode->i_uid to sock_init_data_uid() as the last parameter and     that turns out to not be accurate. (CVE-2023-4194)

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