In the Linux kernel, the following vulnerability has been resolved:
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().
