[PATCH] ALSA: wavefront: fix buffer overflow in longname construction

by moonafterrain＠outlook.com

From: Junrui Luo <moonafterrain(a)outlook.com> The snd_wavefront_probe() function constructs the card->longname string using unsafe sprintf() calls that can overflow the 80-byte buffer when module parameters contain large values. The vulnerability exists at wavefront.c where multiple sprintf() operations append to card->longname without length checking. Fix by replacing all sprintf() calls with scnprintf() and proper length tracking to ensure writes never exceed sizeof(card->longname).

[PATCH] mm/mremap: Honour writable bit in mremap pte batching

by Dev Jain

Currently mremap folio pte batch ignores the writable bit during figuring out a set of similar ptes mapping the same folio. Suppose that the first pte of the batch is writable while the others are not - set_ptes will end up setting the writable bit on the other ptes, which is a violation of mremap semantics. Therefore, use FPB_RESPECT_WRITE to check the writable bit while determining the pte batch.

[PATCH] scsi: aic94xx: fix use-after-free in device removal path

[PATCH] agp/uninorth: fix out-of-bounds access with negative pg_start

by moonafterrain＠outlook.com

From: Junrui Luo <moonafterrain(a)outlook.com> The uninorth_insert_memory and uninorth_remove_memory functions lack proper validation of the pg_start parameter before using it as an array index into the GATT (Graphics Address Translation Table). The current bounds check fails to reject negative pg_start values and potentially causes out-of-bounds writes. Fix by explicitly checking that pg_start is non-negative before performing bounds checking. This makes the security requirement clear and does not rely on implicit type conversion behavior. The uninorth_remove_memory function has no bounds checking at all, so add the same validation there.

However, on AMD systems, only a limited number of RMIDs are guaranteed to be actively tracked by the hardware. RMIDs that exceed this limit are placed in an "Unavailable" state. When a bandwidth counter is read for such an RMID, the hardware sets MSR_IA32_QM_CTR.Unavailable (bit 62). When such an RMID starts being tracked again the hardware counter is reset to zero. MSR_IA32_QM_CTR.Unavailable remains set on first read after tracking re-starts and is clear on all subsequent reads as long as the RMID is tracked. resctrl miscounts the bandwidth events after an RMID transitions from the "Unavailable" state back to being tracked. This happens because when the hardware starts counting again after resetting the counter to zero, resctrl in turn compares the new count against the counter value stored from the previous time the RMID was tracked. This results in resctrl computing an event value that is either undercounting (when new counter is more than stored counter) or a mistaken overflow (when new counter is less than stored counter). Reset the stored value (arch_mbm_state::prev_msr) of MSR_IA32_QM_CTR to zero whenever the RMID is in the "Unavailable" state to ensure accurate counting after the RMID resets to zero when it starts to be tracked again. Example scenario that results in mistaken overflow ================================================== 1. The resctrl filesystem is mounted, and a task is assigned to a monitoring group. $mount -t resctrl resctrl /sys/fs/resctrl $mkdir /sys/fs/resctrl/mon_groups/test1/ $echo 1234 > /sys/fs/resctrl/mon_groups/test1/tasks $cat /sys/fs/resctrl/mon_groups/test1/mon_data/mon_L3_*/mbm_total_bytes 21323 <- Total bytes on domain 0 "Unavailable" <- Total bytes on domain 1 Task is running on domain 0. Counter on domain 1 is "Unavailable". 2. The task runs on domain 0 for a while and then moves to domain 1. The counter starts incrementing on domain 1. $cat /sys/fs/resctrl/mon_groups/test1/mon_data/mon_L3_*/mbm_total_bytes 7345357 <- Total bytes on domain 0 4545 <- Total bytes on domain 1 3. At some point, the RMID in domain 0 transitions to the "Unavailable" state because the task is no longer executing in that domain. $cat /sys/fs/resctrl/mon_groups/test1/mon_data/mon_L3_*/mbm_total_bytes "Unavailable" <- Total bytes on domain 0 434341 <- Total bytes on domain 1 4. Since the task continues to migrate between domains, it may eventually return to domain 0. $cat /sys/fs/resctrl/mon_groups/test1/mon_data/mon_L3_*/mbm_total_bytes 17592178699059 <- Overflow on domain 0 3232332 <- Total bytes on domain 1 In this case, the RMID on domain 0 transitions from "Unavailable" state to active state. The hardware sets MSR_IA32_QM_CTR.Unavailable (bit 62) when the counter is read and begins tracking the RMID counting from 0. Subsequent reads succeed but return a value smaller than the previously saved MSR value (7345357). Consequently, the resctrl's overflow logic is triggered, it compares the previous value (7345357) with the new, smaller value and incorrectly interprets this as a counter overflow, adding a large delta. In reality, this is a false positive: the counter did not overflow but was simply reset when the RMID transitioned from "Unavailable" back to active state. Here is the text from APM [1] available from [2]. "In PQOS Version 2.0 or higher, the MBM hardware will set the U bit on the first QM_CTR read when it begins tracking an RMID that it was not previously tracking. The U bit will be zero for all subsequent reads from that RMID while it is still tracked by the hardware. Therefore, a QM_CTR read with the U bit set when that RMID is in use by a processor can be considered 0 when calculating the difference with a subsequent read."

[PATCH] iio: dac: ad3552r-hs: fix out-of-bound write in ad3552r_hs_write_data_source

by Miaoqian Lin

When simple_write_to_buffer() succeeds, it returns the number of bytes actually copied to the buffer, which may be less than the requested 'count' if the buffer size is insufficient. However, the current code incorrectly uses 'count' as the index for null termination instead of the actual bytes copied, leading to out-of-bound write. Add a check for the count and use the return value as the index. Found via static analysis.

[PATCH] drm/mediatek: fix device use-after-free on unbind

by Johan Hovold

A recent change fixed device reference leaks when looking up drm platform device driver data during bind() but failed to remove a partial fix which had been added by commit 80805b62ea5b ("drm/mediatek: Fix kobject put for component sub-drivers"). This results in a reference imbalance on component bind() failures and on unbind() which could lead to a user-after-free. Make sure to only drop the references after retrieving the driver data by effectively reverting the previous partial fix. Note that holding a reference to a device does not prevent its driver data from going away so there is no point in keeping the reference.
