scsi: lpfc: Fix call trace observed during I/O with CMF enabled
The following was seen with CMF enabled:
BUG: using smp_processor_id() in preemptible
code: systemd-udevd/31711
kernel: caller is lpfc_update_cmf_cmd+0x214/0x420 [lpfc]

this_cpu_ptr() calls smp_processor_id() in a preemptible context.
Fix by using per_cpu_ptr() with raw_smp_processor_id() instead. |

"qemu-ndb -d" will call ioctl 'NBD_DISCONNECT' first, however, following
message was found:
block nbd0: Send disconnect failed -32
Which indicate that something is wrong with the server. Then,
"qemu-nbd -d" will call ioctl 'NBD_CLEAR_SOCK', however ioctl can't clear
requests after commit 2516ab1543fd("nbd: only clear the queue on device
teardown"). And in the meantime, request can't complete through timeout
because nbd_xmit_timeout() will always return 'BLK_EH_RESET_TIMER', which
means such request will never be completed in this situation.
Now that the flag 'NBD_CMD_INFLIGHT' can make sure requests won't
complete multiple times, switch back to call nbd_clear_sock() in
nbd_clear_sock_ioctl(), so that inflight requests can be cleared. |

nbd: call genl_unregister_family() first in nbd_cleanup()

| In the Linux kernel, the following vulnerability has been resolved:
cifs: prevent bad output lengths in smb2_ioctl_query_info()
When calling smb2_ioctl_query_info() with
smb_query_info::flags=PASSTHRU_FSCTL and
smb_query_info::output_buffer_length=0, the following would return
0x10
buffer = memdup_user(arg + sizeof(struct smb_query_info),
qi.output_buffer_length);
if (IS_ERR(buffer)) {
kfree(vars);
return PTR_ERR(buffer);
}
rather than a valid pointer thus making IS_ERR() check fail. This
would then cause a NULL ptr deference in @buffer when accessing it
later in smb2_ioctl_query_ioctl(). While at it, prevent having a
@buffer smaller than 8 bytes to correctly handle SMB2_SET_INFO
FileEndOfFileInformation requests when
smb_query_info::flags=PASSTHRU_SET_INFO.
Here is a small C reproducer which triggers a NULL ptr in @buffer when
passing an invalid smb_query_info::flags

| In the Linux kernel, the following vulnerability has been resolved:
media: s5p_cec: limit msg.len to CEC_MAX_MSG_SIZE
I expect that the hardware will have limited this to 16, but just in
case it hasn't, check for this corner case. |
| The LiteSpeed Cache plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via URLs in all versions up to, and including, 7.5.0.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. |
| The Easy Testimonial Slider and Form plugin for WordPress is vulnerable to SQL Injection via the 'id' parameter in all versions up to, and including, 1.0.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. |
| The Thumbnail Slider With Lightbox plugin for WordPress is vulnerable to SQL Injection via the 'id' parameter in all versions up to, and including, 1.0.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. |
