fbdev: tridentfb: fix potential memory leak in trident_pci_probe()

2026-07-24T13:54:59+00:00

commit 7a35ec619d9af8ee128320975c1252b8ad65f1e8 upstream. In trident_pci_probe(), the memory allocated for modelist using fb_videomode_to_modelist() is not freed in subsequent error paths. Fix that by calling fb_destroy_modelist().

fbdev: tdfxfb: fix potential memory leak in tdfxfb_probe()

2026-07-24T13:54:59+00:00

commit bb019d755366cc3e777a12d4bf457ff289837370 upstream. In tdfxfb_probe(), the memory allocated for modelist using fb_videomode_to_modelist() when CONFIG_FB_3DFX_I2C is defined, is not freed in the subsequent error paths.

fbdev: uvesafb: fix potential memory leak in uvesafb_probe()

2026-07-24T13:54:59+00:00

commit 033e56fed09047ee63072e9f58789f40c1c7079d upstream. Due to an incorrect goto label, memory allocated for modedb and modelist in uvesafb_vbe_init() is not freed in some error paths. Fix this by updating the goto label.

commit 5936063409af230a2c88b8700c47b89a19fd70b5 upstream. In i740fb_probe(), the memory allocated in fb_videomode_to_modelist() for modelist is not freed in the error paths.

fbdev: radeon: fix potential memory leak in radeonfb_pci_register()

2026-07-24T13:54:58+00:00

commit df8c1101c9a08859da612b5d0a08d55d475522c6 upstream. The function radeonfb_pci_register() allocates memory for modelist (by calling radeon_check_modes() which calls fb_add_videomode()). The memory is appended to info->modelist, but is not freed in subsequent error paths. Fix this by calling fb_destroy_modelist().

fbdev: sm712: Fix operator precedence in big_swap macro

2026-07-24T13:54:58+00:00

commit 5dbe5b65df0b0c0ec77492427c274b7b5011890e upstream. The big_swap(p) macro was intended to swap bytes within 16-bit halves of a 32-bit value. However, because the bitwise shift operators (<<, >>) have higher precedence than the bitwise AND operator (&), the original code failed to perform any shifting on the masked bits. For example, 'p & 0xff00ff00 >> 8' was evaluated as 'p & (0xff00ff00 >> 8)', effectively neutralizing the intended swap. Fix this by adding parentheses to ensure the bitwise AND is performed before the shift, correctly implementing the byte swap logic.
