CVE-2024-50071 |
Description: In the Linux kernel, the following vulnerability has been resolved:
pinctrl: nuvoton: fix a double free in ma35_pinctrl_dt_node_to_map_func()
'new_map' is allocated using devm_* which takes care of freeing the
allocated data on device removal, call to
.dt_free_map = pinconf_generic_dt_free_map
double frees the map as pinconf_generic_dt_free_map() calls
pinctrl_utils_free_map().
Fix this by using kcalloc() instead of auto-managed devm_kcalloc().

CVE-2024-50065 |
Description: In the Linux kernel, the following vulnerability has been resolved:
ntfs3: Change to non-blocking allocation in ntfs_d_hash
d_hash is done while under "rcu-walk" and should not sleep.
__get_name() allocates using GFP_KERNEL, having the possibility
to sleep when under memory pressure. Change the allocation to
GFP_NOWAIT.

CVE-2024-50062 |
Description: In the Linux kernel, the following vulnerability has been resolved:
RDMA/rtrs-srv: Avoid null pointer deref during path establishment
For RTRS path establishment, RTRS client initiates and completes con_num
of connections. After establishing all its connections, the information
is exchanged between the client and server through the info_req message.
During this exchange, it is essential that all connections have been
established, and the state of the RTRS srv path is CONNECTED.
So add these sanity checks, to make sure we detect and abort process in
error scenarios to avoid null pointer deref.

CVE-2024-50059 |
Description: In the Linux kernel, the following vulnerability has been resolved:
ntb: ntb_hw_switchtec: Fix use after free vulnerability in switchtec_ntb_remove due to race condition
In the switchtec_ntb_add function, it can call switchtec_ntb_init_sndev
function, then &sndev->check_link_status_work is bound with
check_link_status_work. switchtec_ntb_link_notification may be called
to start the work.
If we remove the module which will call switchtec_ntb_remove to make
cleanup, it will free sndev through kfree(sndev), while the work
mentioned above will be used. The sequence of operations that may lead
to a UAF bug is as follows:
CPU0 CPU1
| check_link_status_work
switchtec_ntb_remove |
kfree(sndev); |
| if (sndev->link_force_down)
| // use sndev
Fix it by ensuring that the work is canceled before proceeding with
the cleanup in switchtec_ntb_remove.

CVE-2024-50058 |
Description: In the Linux kernel, the following vulnerability has been resolved:
serial: protect uart_port_dtr_rts() in uart_shutdown() too
Commit af224ca2df29 (serial: core: Prevent unsafe uart port access, part
3) added few uport == NULL checks. It added one to uart_shutdown(), so
the commit assumes, uport can be NULL in there. But right after that
protection, there is an unprotected "uart_port_dtr_rts(uport, false);"
call. That is invoked only if HUPCL is set, so I assume that is the
reason why we do not see lots of these reports.
Or it cannot be NULL at this point at all for some reason :P.
Until the above is investigated, stay on the safe side and move this
dereference to the if too.
I got this inconsistency from Coverity under CID 1585130. Thanks.

CVE-2024-50049 |
Description: In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check null pointer before dereferencing se
[WHAT & HOW]
se is null checked previously in the same function, indicating
it might be null; therefore, it must be checked when used again.
This fixes 1 FORWARD_NULL issue reported by Coverity.

CVE-2024-50048 |
Description: In the Linux kernel, the following vulnerability has been resolved:
fbcon: Fix a NULL pointer dereference issue in fbcon_putcs
syzbot has found a NULL pointer dereference bug in fbcon.
Here is the simplified C reproducer:
struct param {
uint8_t type;
struct tiocl_selection ts;
};
int main()
{
struct fb_con2fbmap con2fb;
struct param param;
int fd = open("/dev/fb1", 0, 0);
con2fb.console = 0x19;
con2fb.framebuffer = 0;
ioctl(fd, FBIOPUT_CON2FBMAP, &con2fb);
param.type = 2;
param.ts.xs = 0; param.ts.ys = 0;
param.ts.xe = 0; param.ts.ye = 0;
param.ts.sel_mode = 0;
int fd1 = open("/dev/tty1", O_RDWR, 0);
ioctl(fd1, TIOCLINUX, ¶m);
con2fb.console = 1;
con2fb.framebuffer = 0;
ioctl(fd, FBIOPUT_CON2FBMAP, &con2fb);
return 0;
}
After calling ioctl(fd1, TIOCLINUX, ¶m), the subsequent ioctl(fd, FBIOPUT_CON2FBMAP, &con2fb)
causes the kernel to follow a different execution path:
set_con2fb_map
-> con2fb_init_display
-> fbcon_set_disp
-> redraw_screen
-> hide_cursor
-> clear_selection
-> highlight
-> invert_screen
-> do_update_region
-> fbcon_putcs
-> ops->putcs
Since ops->putcs is a NULL pointer, this leads to a kernel panic.
To prevent this, we need to call set_blitting_type() within set_con2fb_map()
to properly initialize ops->putcs.
