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. • https://git.kernel.org/stable/c/f4149eec960110ffd5bcb161075dd9f1d7773075 https://git.kernel.org/stable/c/c643ef59390e49f1dfab35e8ea65f5db5e527d64 https://git.kernel.org/stable/c/97a79933fb08a002ba9400d1a7a5df707ecdb896 https://git.kernel.org/stable/c/65b2d49e55fe13ae56da3a7685bdccadca31134a https://git.kernel.org/stable/c/a9b4fd1946678fa0e069e442f3c5a7d3fa446fac https://git.kernel.org/stable/c/ff599ef6970ee000fa5bc38d02fa5ff5f3fc7575 •

https://notcve.org/view.php?id=CVE-2024-50048
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. • https://git.kernel.org/stable/c/8266ae6eafdcd5a3136592445ff4038bbc7ee80e https://git.kernel.org/stable/c/f7fb5dda555344529ce584ff7a28b109528d2f1b https://git.kernel.org/stable/c/e5c2dba62996a3a6eeb34bd248b90fc69c5a6a1b https://git.kernel.org/stable/c/5b97eebcce1b4f3f07a71f635d6aa3af96c236e7 •
