Tenable has extracted the preceding description block directly from the EulerOS kernel security advisory.

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.

  - netdevsim: Fix memory leak of nsim_dev->fa_cookie kmemleak reports this issue: unreferenced object     0xffff8881bac872d0 (size 8): comm sh, pid 58603, jiffies 4481524462 (age 68.065s) hex dump (first 8     bytes): 04 00 00 00 de ad be ef ........ backtrace: [<00000000c80b8577>] __kmalloc+0x49/0x150     [<000000005292b8c6>] nsim_dev_trap_fa_cookie_write+0xc1/0x210 [netdevsim] [<0000000093d78e77>]     full_proxy_write+0xf3/0x180 [<000000005a662c16>] vfs_write+0x1c5/0xaf0 [<000000007aabf84a>]     ksys_write+0xed/0x1c0 [<000000005f1d2e47>] do_syscall_64+0x3b/0x90 [<000000006001c6ec>]     entry_SYSCALL_64_after_hwframe+0x63/0xcd The issue occurs in the following scenarios:
    nsim_dev_trap_fa_cookie_write() kmalloc() fa_cookie nsim_dev->fa_cookie = fa_cookie .. nsim_drv_remove()     The fa_cookie allocked in nsim_dev_trap_fa_cookie_write() is not freed. To fix, add     kfree(nsim_dev->fa_cookie) to nsim_drv_remove(). (CVE-2022-49803)

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